At the Diaz household, a cassette radio plays La Calaca Feliz.

Marco was lazily sitting in a lawn chair while eating some of his home-made nachos. He starred off in to space with a face of boredom and disappointment.

"I'll have my own blood moon Ball in Star's bedroom, where it's always fun." He says mockingly while do a gesture with his arms.

He grabs another handful of nachos and stuffs them in his face and chews. He stops and looks behind him, seeing the blood moon. Star was there, with Tom. He didn't trust Tom. He had even heard of him until earlier that day. Tom was a guy that Star dated at some point on Mewni. For how long they dated, Marco didn't know. But he did know that she broke up with him for a good reason and that guys like Tom don't usually don't change. It didn't make any sense. Why would Tom, a person who hasn't seen Star in months and Star broke up with, suddenly ask her to this demon dance? It sounded fishy to Marco. But Star made her decision, regardless of Marco's concerns, and he wasn't going intervene.

After staring at the moon and thinking about it, he went back to eating his nachos.

"Blood Moon tonight." A gruff voice says.

Marco immediately stops what he's doing, wide eyes.

What was that?

He looks from side to side, trying to find where the voice came from. He doesn't see anybody else in the room. But he notices a portrait of a captain of a ship. He eyed it suspiciously for short while. But it doesn't move, nor make a noise.

It must have just been his imagination. He went back to casually eating nachos.

"The moon of lovers." The voice says again.

Marco goes bug eyed again and stands up. He looks straight at the portrait of the captain. It still hadn't moved.

Marco thinks about what it said. Blood Moon tonight. The moon of lovers.

He didn't know what that meant. But Star being at the moon of lovers with a questionable person worried Marco.

He looks at the bed stand to his left where he sees that the bell Tom gave Star to call the chariot that took her to the blood moon Ball was still there. Marco looks at it, thinking.

At the blood moon Ball.

Star eagerly watches a punch bowl full of blood.

"Here he comes again." She says just before the skeleton of a fish hops out of the blood.

"Hello Henry!" She says to a goblin nearby.

"I named him Henry" She says as she points at the fish skeleton.

"You must be Tom's date." A voice behind her says.

Star turns around to find two monsters looking at her.

"I guess I am." She says without confidence.

The monster to the left of the other resumes talking to her.

"Well, I hope you're happy. He made this whole entire ball completely boring, all for you." The monster rudely says to her.

"I wouldn't say it's boring." Star says back.

"Oh really?" The monster questions.

"Aloof attractive people. Boring!" He says while pointing at two dating blue demons.

He hops out of the punch bowl.

"Bubbling cauldrons that don't even melt your flesh off. What is it, nap time or something? 'Cause I'm bored!"

Points at an empty garbage cup on the ground.

"Piece of garbage that doesn't destroy the universe. Stupid cockroach that lives inside. I'm over it already!"

The monster begins sobbing and proceeds to run away, leaving the other monster by himself. He looks at Star.

"You want to dance?" He asks.

Tom, instantly appearing from midair at the perfect time to say, "Her dance card's full."

"Oh, I get it." The monster says. "I bet you think that, like, your soul and, like, her soul are totally gonna mmmmmmmm!" He says while slowly interlocking his fingers in each other.

"What is mmmmmmmm!" She asks while re-enacting the same gesture with her hands, but is interrupted by the host tapping the microphone.

"Ahem. Good evening, ladies and gentlebremen. It is my pleasure that I request you now to turn your heads skyward.

A large hand with a diamond shaped window in the palm of it begins to protrude out of the ceiling. The host continues talking.

"When the light of the blood moon drubbles down and selects two lucky souls, binding them together for eternity in its hypnotic, ruby brodum." He finishes.

"Wow." Star says slowly while in awe of the window of which the blood moon will shine through.

An organist begins playing a slow and creepy piece of music while the light of the blood moon slowly creeps towards the center of the window.

"Ugh! That's the wrong piece of music! This is gonna drive me crazy. Alright, don't go anywhere. I'll be right back." Tom says, frustrated, to Star.

"Okay." Star quickly replies as not a moment after, she wanders away.

"Oooooh." She exclaims as she walks past a group of dancers. Marco, wearing a black tuxedo, a sombrero and Día de los Muertos mask emerges from behind the group.

He looks around for Star, calling her name. "Star!" However, he cannot be heard.

Star looks around the ballroom dance floor, still in awe of the scene. Marco finds her and begins to follow her, whispering her name to try to get her attention.

He finally catches ups to her, grabs her hand and pulls her around, bringing the two of them into a waltz pose.

The music stops and all of the lights go out. Except for a red spotlight that is directed right on the two of them. Everyone at the ball gasps.

The two of them stare at each other in disbelief at the situation. They stood there, perfectly still.

The blood moon waltz music begins playing.

In spite of their shock, they begin to waltz in the middle of the dance hall, while everyone else stops what they're doing and watches the two selected by the blood moon.

As the two begin to waltz around the room, Marco leads Star into a spin, making Star gasp with surprise. As they spin, the two look at each other. Marco is in utter shock of the situation and can't even speak. Star is also shocked at the turn of events, but she has also shocked with amazement of her newly found dance partner. She stares at him, a very handsome man with a beautiful face mask, not knowing his true identity. Her lips slowly move into the shape of large smile as she falls in to a dreamy state while dancing with her amazing mystery dance partner.

The two continue to dance in the light of the blood moon. At the back of the crowd, Tom notices that his date is dancing with a different person. He gasps, then quickly fills with anger and growls aggressively.

As the two continue dancing, Marco watches and observes Star's facial expression of absolute awe of him. Star's face was struck with wonder and amazement as she stared him right in the eyes.

"Who are you?" She asked dreamily.

For a brief moment, Marco considers taking off the mask and convincing her to leave the blood moon ball immediately. However, he reconsidered. Star was looking forward to the blood moon ball, and she was currently enjoying herself right now. She also didn't want Marco to come in the first place, she would be upset that he didn't listen to her and came anyways because he didn't fully trust her on her own. But more than anything, Marco didn't want to stop dancing with Star. Every moment that he danced with Star, he loved dancing more and more. It was one of the most magical things he had ever done. He never answered Star's question. He continued to dance with Star, not saying a single word.

Star was in a world of her own as she was going googly eyes for her amazing mystery dance partner who kept quiet and never revealed his name. She adored his black and gold Tuxedo and his beautifully made face mask of a colored skull. She had just met this person, and he was already the most amazing person she had ever met.

As the two of them swung around and tossed on of their arms out each, they looked in to each other's eyes. Star looked at his beautiful brown eyes that looked right in to her own. They were the most amazing things she had ever seen. However, they looked a little familiar to her.

Out of nowhere a loud growling was heard right next to Marco and the music suddenly stopped. Marco averted his eyes to the sound of the noise just to see Tom shove and push him right down on to the ground, separating him from Star.

Where Marco once stood, Tom now stood, growling with frustration. He looks up to notice the spot light of the blood moon closing on him, returning the rest of the room to normal light.

He looks back at the one who stole his dance with Star, who is now sitting up on the ground. Tom's eyes begin glowing as he fills with rage.

Marco gets up and moves his sombrero so he can see, only to see Tom as he steps towards him, his face displaying immense hatred.

"That dance was meant FOR ME!" Tom yells as the entire room is surrounded by an enormously tall ring of fire.

Tom's life coach quickly rushes over.

"Walk it ou-"

"No Brian!" Tom grabs Brian by the face and shoves him away.

Star watches Tom filled with aggressive anger as he walks towards her former dance partner. She watches him slowly scoot away from Tom in fear. She knew exactly what Tom was going to do her partner.

Tom gets close to Marco and then launches in to the air, yelling.

Marco flinches and puts his arm up in an attempt to soften the expected blow from Tom

"Aaaaaaahhhhhh-" Tom screeches.

A beam of magic hits Tom mid-air, freezing him in a giant block of ice.

It lands right beside Star, who is now holding her wand out pointed at frozen Tom. She slowly walks over to Tom in the ice cube and then zaps it with her wand, putting a little sticker on it saying, "0 Days Anger Free." She stares at Tom with disappointment and anger. She then sighs and looks at her not-frozen-but-shaken-up-former-dance-partner.

"I'm really sorry for Tom's crazy outburst and attempt of killing you." She says to him apologetically as he gets up and dusts himself off. She then quickly shoves frozen Tom and he slides to and hits the wall at the back of the room.

Marco looks around awkwardly, then turns back to Star and shrugs. He breaks a little sweat, this happened to quickly and caught him off guard.

Star walks toward him, grabs one of his hands and looks him in the eyes.

"I probably don't deserve to ask this because my ex tried to burn you alive, but do you think we could pick up off where we left off and finish dancing? You're such an amazing person and dancer." She asks him while giving him the cute, sad eyes face.

Marco pauses and blinks for a moment. She still had no idea who he was. He thought she would've figured it out by now because of the black hair and Mexican themed mask he was wearing. But he didn't want to upset Star.

He nodded slowly.

Star gasped loudly and brought her hands to her cheeks while her eyes sparkled with delight.

"Yay!" She cried loudly.

She turned around and yelled, "Hey! Piano guy! Play that song again, please!"

"Uh, okay." The organist said.

"Thanks!" She replied.

The blood moon theme resumed and both and Marco and Star grasped each other's hands and begin slowly dancing. The coupled danced all around the ballroom, their dances matching the smooth, soft sound of the piano notes with a choir of voices quietly humming as the two were lost in each other's eyes. Marco pulled Star in to a slow, majestic twirl as the sound of bell chimes strummed up and down making it feel like a dream.

As the music continued and the two of them continued dancing, the rest of the crowd at the ball began to resume dancing with the rest of their partners. The music continued and so did Star and Marco's dancing. Every move that Star and her partner made felt so natural, like they had done this many times before and perfected it. But she had never danced with this mysterious person before, at least so she thought.

Soon, the music began to come to an end. The two's dancing slowed down as did the music. The did their last steps and swings, the last sounds of piano keys matching their every action. Each of them closed their eyes and slowly spun around one last time. When they opened their eyes, they saw each other's faces, just inches apart from each other. They breathed heavily, both thinking the same thing. Star closed her eyes again and slowly moved her face towards Marco's. Marco just starred for a moment, thinking about everything that happened that night. He didn't know how to feel. He felt happy, yet he felt so guilty. But he pushed that all to the back of his mind. He closed his eyes and slowly moved his face towards Star's. Their lips connected, softly and slowly, and just for a moment, as the last piano note played.

They pulled apart from each other and both slowly opened their eyes. They were both awestruck.

"Wow." Star said dreamily. "You're amazing."

Marco just stood there, wide eyes, filled with amazement. He didn't say a word. His face behind the mask said it all.

The just stood there in silence. They still couldn't believe what happened. Eventually, Star spoke up.

"Hey, that was one amazing dance, but it was also really exhausting." She said while blushing. "I'm gonna go grab some punch and I'll be right back."

Star awkwardly backed away a couple of steps and then turned around to go to the punch bowl.

Marco stood there for a brief moment, only to shake his head moments later. What was he doing? How did this happen? He shouldn't be here. If Star goes back, which she will, he won't be home. What would she think? He'd have to explain that he dressed up and came to the dance despite Star telling him not to, reveal that he danced with her and upset Tom beyond belief. Oh yeah, and he kissed her. That would be a really awkward moment for two friends.

He looked around quickly. He had to get out of here.

Marco looked around, trying to find where he came in from. He found it. And he left immediately.

Star returns.

"It looks like that guy from before spilled all the punch, but that's okay be-" She was saying, but stopped when she realized her dance partner was nowhere to be found.

"Um, mystery guy. Where'd you go?" She asked out loud. "Mystery guy!"

She looked around the entire ballroom, but couldn't find him. She asked every person she could find at the ball, but nobody knew where here mystery man went off to. She sighed and then walked towards the exit.

However, she wasn't upset. When she hopped in the chariot she originally arrived in, she had a huge grin on her face. During the drive home, she thought about the night she had just had. She was so enamored by the man with the mask. He was such an amazing guy, she couldn't stop thinking about him for the entire ride home.

The chariot eventually arrived back at the Diaz house in a flaming burst of fire.

"You are home, mortal." The driver said to her, bringing her out of her dreamy trance.

"Oh, yeah. Thanks for the lift!" She replied cheerily.

She stepped off the chariot and on to the balcony and walked in to her room as the chariot left in a burst of fire.

Marco was sitting on a lawn chair, listening to the radio and eating nachos. He was wearing his signature red hoodie. He then noticed that Star was here.

"Uh- Star! You're back! How was the blood moon ball? Did you have a good time with Tom?" He replied a little nervously. However, Star didn't even notice.

"You were right about Tom, Marco. Some people don't ever change." She said while still wearing a grin on her face.

"Oh, that's unfortunate. Did Tom ruin-" Marco was beginning to say, but was interrupted.

"It was amazing. I ditched Tom and danced with someone else. The most amazing guy in the world." She blurted out all romantically. "I didn't even know who he was, but he was the greatest. He had the most beautiful eyes, he was the best dancer I have ever met, and he wore the most amazing looking mask on his face."

"Star, you shouldn't dance with person who hides-" Marco began to say.

"He never spoke a word to me. Yet he had so much personality." She said while looking out the balcony window. "It was the best moment of my life."

"Okay. Well, uh, maybe we should get some sleep. You look tired, Star." Marco said.

"Yeah, yeah. Sure thing, Marco." Star replied, not paying attention to Marco because she was off in dreamland again.

Star slowly walked over to her bed and then flopped down right on to it and let out a long sigh.

Marco walked to the door of her room and opened it. He turned around and said, "Goodnight, Star."

"Goodnight, Marco." She said sweetly with her eyes closed. She began to quietly hum herself to sleep.

Marco left and closed the door behind him. He walked into his room and closed the door behind him. He sighed. How did this night unfold like this? He lied down in bed and tried to sleep. But he couldn't.

All he could do is stare at the red blood moon all night long, until it disappeared behind the horizon.
