~Isabella's POV~

I walked into my art class, with dried tears on my face. I couldn't help, but play the flashback in my head over and over again.

~flashback~

Isabella walked down the hall. A new guy, seen her," Hey you!" Isabella turned around," Yes?" "Can you show me around?" Isabella smirked. She knew what he was up to," Nope, sorry." She continued walking but he ran after her and took her arm," Well maybe you can after this." He kisses her. She doesn't kisses back and hits his chest to tell him to get off. Phineas sees them," What the hell is going on?" Isabella pulls away and slaps the new guy," Phineas it's not what you-" "You know what Isabella, forget it! Don't talk to me ever again!" He walks away.

~Isabella's POV~

I finally paid attention. To what my teacher was saying but it was too late because the bell rung. I grabbed my bag and hurried out of the room. It was about time for lunch but I didn't go straight to the lunch room. I headed inside the bathroom and got out my razor that I usually keep in case I have to shave. I raised up my wrist and started to cut myself. I then put my razor away and put my sweater on so nobody could see them.

I decided to eat in the school's garden. Which is the place, where I eat to get my mind off things. I liked the quiet. It calmed me.

"Are you okay, Isabella?" Ferb said concerned. "Why would you care? Aren't you supposed to be supporting your brother?" Isabella wasn't facing Ferb, so he didn't see her cry. "Isabella, your still my friend. No matter what." "Good to here Ferb but I'm busy planning the murder of the mystery guy right now..." Isabella was playing but really did want to hurt the mystery new guy. Ferb laughed," You didn't want to kiss him did you?" "You think? And why are laughing?" "Because, after all these years, Phineas doesn't believe you." " Whatever, it doesn't matter anymore... He doesn't love me anymore." She put her hands up in defense revealing her cuts. Ferb grabbed her wrist," What's this?" Isabella rolled her sleeves down," N-Nothing, look I have to go so..." She left with tears in her eyes. She decided to skip school for the rest of the day and went to the beach.

In history, Gretchen looked around seeing an empty seat where Isabella was supposed to be," Ferb?" Ferb looked at her," Where is isabella?" He shrugged his shoulders. He was wondering the same thing.

After school, The gang was hanging in the Phineas and Ferb's front yard. There was an awkward silence between everyone, because of Phineas. Isabella was walking home. Isabella was looking for her key and couldn't find it. Phineas realized that he had her key but didn't wanna say anything. Isabella tried knocking on the door, but no one answered. Isabella sighed, and called her mom. " Hello?" "Mom, I lost my key." "Try under the mat." Isabella looked under the mat and there was no key," There's no key." "Uh try the plant?" Isabella reached in the plant. "No key." "Well the back door should be open." "Okay mom." Isabella hung up and walked into her backyard. "You had her key didn't you?" Ferb said disappointed. "Yea..."

Isabella opened her back door and sighed. She knew Phineas had her key but she didn't wanna go over. Isabella sat in her room and listened to the voice within - by Christina Aguilara.

Phineas and Ferb sat in their backyard later on that day. Phineas turned to Ferb," Hey, Ferb! Have you talk to...her?" Ferb looked at him, and nodded to him sadly. "What did she say?" Ferb looked down, " Before I say anything else, did you let her at least explain?" "No..." " I would think you knew her better than cheating on her." Ferb shook his head then went inside.

The next day, Isabella wore a bunch of bracelets on her arms. She sat on a bench in the hallway and was doing her homework. Gretchen and Adyson sat down next to her," Didn't do your homework?" Adyson teased. " Yea. When I got home I didn't have my key so I had to go through the back. Next, I had to clean up because pinky peed and pooped all around the house. Then, my mom was late, so I had to cook dinner. After that, I didn't get any sleep at all last night because I was thinking about...him!"
