The class had went for a beach trip. All Might had suggested it to the faculty and got overwhelming support from most of the staff. Once all the important stuff had been organised, the class was driven down to the beach after classes on Saturday.

Many of them rushed onto the sand almost immediately, sprinting straight into the sea with no abandon. Others held back, actually setting up a spot on the sand to rest.

Midoriya had laid out his mat and positioned his umbrella just-so perfectly so he wouldn't be blinded before dropping down onto the mat. He clicked open his suncream bottle and started to rub the liquid onto his bare skin.

"Yo Izuku! Can I borrow some?" Kirishima called as he jogged over.

"Y-yeah sure Ei, I'm just p-putting the last of it on."

"Need help with your back? I know I struggle to properly do mine so..."

"O-only if you want to."

Kirishima gently took the bottle from Midoriya, putting some onto his hand before coating his boyfriend's back. His hands snuck around to Midoriya's stomach, pulling the boy in closer to him. Midoriya squeaked in surprise before Kirishima pressed a small kiss to Midoriya's cheek.

"E-Ei!"

"Sorry, I couldn't resist." Kirishima apologised before handing Midoriya the bottle back. "I've finished your back."

"T-that's good. I-I'll do your back in r-return?"

"That'd be lovely." Midoriya started to put the cream on Kirishima's back, who in turn grabbed some and did the rest of his body.

"Hurry up gays! We're all off to have some competitions!" Jirou shouted across to them from where she stood with most the other girls.

"Coming Jirou!"

"D-did she say gays?"

"Yup." Kirishima answered with a laugh before standing up and holding a hand out for Midoriya. "You ready?"

"Yeah," Midoriya replied, taking Kirishima's hand and letting himself be pulled up.

The pair walked hand in hand towards the rest of their classmates, half soaking wet from the water.

And the contests started.

The first contest was building a sandcastle, and (sadly for Midoriya and Kirishima) they were separated.

"But-"

"Deku all the couples have been split up," Uraraka explained, "so it's fine."

Midoriya pouted before relenting, getting a giggle from Uraraka. She quickly turned around towards the opposition and waved to Ashido.

"Mina, babe!"

"Yeah Ochako?"

"We're gonna kick your ass!"

"Oh you are on. This is war!"

The pair giggled before turning back to their own teams.

"Let's do this guys!" Kaminari cheered, the rest following suit.

It was a close match; All Might, Present Mic and Midnight had a difficult time choosing a winner (Aizawa didn't help judge as he would rather have a nap in the shade). But ultimately, the other team won simply because of Yaoyorozu and her knowledge made a far more stable structure for their sandcastle.

It was a swimming race next, and their hopes were high. Midoriya's team had Asui in it after all, so they were almost a shoe in for victory.

And it was true. They finished a great deal ahead of the other team (Mineta was a poor swimmer so Midoriya almost felt pity for the other team. almost).

"Alright young listeners! Pair up for a mini-cavalry battle!" Present Mic announced.

Midoriya sped towards Kirishima the moment Present Mic finished speaking. Kirishima noticed his movements and closed the gap between them.

"I could lift you up?" Midoriya suggested.

"Ok Izuku, I trust you not to let me fall."

"I won't let you down Ei!"

"I know you won't."

The pair quickly discussed tactics before heading to the waters edge.

("Come on Bakugou, I could use my quirk to make you lighter so I can carry you easily! Then you can knock everyone over and we can win and be the best in class!" Uraraka persuaded Bakugou, who smirked at the thought of winning.

"It's a deal Uraraka." He said, grabbing her wrist towards the group of pairs ready.)

Eventually, they had all paired up and one by one, the pairs entered the water.

"Ready? Go!" Present Mic announced and Midoriya sped into the fray. He took notice of those around him and what they were doing, who they planned to attack.

"Izuku go right! Let's get Mineta and Shouji out!" Kirishima said. Midoriya nodded as he ran (or as best as he could) through the water to the pair. "Surprise!" Kirishima shouted as they sped into them, Kirishima's hands pushing Mineta as they collided.

They succeeded in knocking the other two out, Mineta screeching as he toppled off of Shouji's shoulders.

"Mineta and Shouji out!"

""Yes!"" The pair shouted in victory.

"Ashido and Asui out!"

"That was a dirty move Ochako, kissing me then pushing us over." Ashido complained as she and Asui stood up slowly, cheeks flushed.

"All's fair in love and war." Uraraka teased with a wink before carrying Bakugou off to knock another pair over.

"Kouda and Tokoyami out!"

"Sero and Kaminari out!"

"Hagakure and Ojirou out!"

"Aoyama and Satou out!"

"Todoroki and Iida out!"

The three teams left stood in a circle, staring one another down.

"Come on Bakugou, let's take down the couples!"

"Yaomomo! Let's do this!"

"Ei! We can do it!"

They rushed in all at once, the classmates stood on the shore shouting support for the different pairs.

It all happened very fast.

Kirishima managed to nudge Bakugou and Uraraka slightly, pushing them away before going for Jirou and Yaoyorozu.

The girls fell.

"Yaoyorozu and Jirou out!"

Kirishima and Midoriya paused for a second, revelling in their victory.

Or at least they did before getting a face full of water. Midoriya coughed as he stood up, shaking his head to get orientated again.

"Huh?"

"Kirishima and Midoriya out! The winners are Bakugou and Uraraka!"

"Oh fuck yes!" Bakugou cheered. Uraraka reached a hand up and Bakugou high-fived it.

"We won!" Uraraka celebrated, the victors walking to the shore whooping and hollering.

"Ei, are you ok?" Midoriya asked, hand held out to his boyfriend. He took it, pulling himself up.

"Yeah I'm fine. Shame we didn't win but we shouldn't have let them get behind us."

"I'm sorry Ei, I should've paid more attention. Sorry I let us down."

"Izuku, you could never let me down. It's just a little game. Come on, let's go to the others." Kirishima said, hand on Midoriya's shoulder in support.

"Yeah, your right. Let's go." Midoriya replied, smile on his face.

Holding hands, the pair headed back to the others.

"Took you guys long enough! Keep your making out until later." Kaminari said playfully, laughing at Midoriya's face going red all the way to his ears.

The last 'activity' was a campfire on the shore, Todoroki lighting it with his quirk as the sun started to set.

While the group waited for the teachers to get everything set up, Midoriya and Kirishima wandered away from the group a little.

"It's a nice sunset." Midoriya commented as they strolled side by side, hand in hand.

"Yeah, it's a nice sight... thought not as nearly as nice a sight as you." Kirishima said in a flirty tone.

"E-Ei! You can't just say that!"

"I can and I will. Am I not allowed to say that my boyfriend, who I love so very much, is handsome, amazing and wonderful."

"Y-you love me?"

Kirishima froze, realising what he said, going as red as some of his classmates sunburn.

"Y-yeah. I've known for a while but I never really had the guts to say it to you. I know we've done some scary stuff, scarier than saying three words but it was hard ya know?"

"I get it. I've been wanting to say it as well for a long time." Midoriya admitted, scratching his cheek slightly with his scarred hand. "S-so... I guess I finally should say it... I love you, Ei."

"I love you too Izuku."

The two pressed their foreheads together as the last few rays of the sun sank beneath the horizon.

"The sunset reminds me of your hair," Midoriya breathed, "though I think your hair is a nicer colour."

"Jeez Izuku, and I couldn't say your prettier than the sunset."

"That's because-"

"You two lovebirds! You're gonna miss the campfire and all the marshmallows!" Uraraka called, arm wrapped around her girlfriend.

"Coming Uraraka!" Midoriya shouted before turning back to Kirishima. "We can flirt later."

"Or we can flirt in front of everyone and make them super hella jealous of our love?"

"W-while I'd love to do that, I'd rather not get explodo-killed by Kacchan today."

Kirishima laughed before they sat down in the circle around the campfire between Ashido and Todoroki, a marshmallow and a skewer handed to the both of them.

As they roasted their marshmallows, almost lighting them on fire, there was only one thought in each of their minds.

I love you.
