(Psycho: Please don't mind if ANY Characters are acting OOC (Out OF Character) and that I basically don't know anything about Seasickess. I've only ever had it one time and that was just me getting hella dizzy)

Class 1A is going on a class trip to a place called Sindria, to meet King Sinbad who has taken a liking to them.

But what none of them know is that one of their classmates have seasickness, and that is quite the problem when they're going by boat on a cruise ship, AND is the Adopted Son of the King, but only the King and the Eight Generals know that.

Right now, Class 1A is boarding the Cruise ship called KatsuIzu (Psycho: Yes, that is the best Ship name I could come up with)

Ochaco: "Yosh! I'm so excited!" she said jumping around

Iida: "Uraraka! Would you please refrain from jumping so close to the water!"

Ochaco: "Yeah, Yeah," she said scratching her neck

Intercom: [We will be boarding the Ship soon. Please get your belongings ready for boarding. *Beep*]

Aizawa: "Okay kids, get your stuff and get ready to board." he said in a tired voice as he laid down in his sleeping bag.

The class is now on the deck of the ship some of them are playing in the pool, some are sunbathing and some are doing other stuff like Katsuki, who are just looking at Izuku who looks a bit pale and has been standing close to the railing ever since they got aboard the ship.

Suddenly Izuku ran away into the Ship and Katsuki seemed to be the only one to notice so he followed after to make sure that 'The Shitty Nerd' didn't hurt himself.

When Katsuki finally finds Izuku, Izuku is hunched over a toilet emptying his stomach's contents.

Katsuki: "What fuck deku!? Where the fuck is your pills!?"

Izuku finally stopped puking and turned his head around with a pale face

Izuku: "I forgot them at home and none of the crew have any, nor does anyone else in the class have seasickness so I'm the only one."

Katsuki: "Dammit Deku"

Katsuki picked Izuku up bridal style and started walking

Izuku: "Ka-Kacchan! What are you doing!?" He said wriggling around

Katsuki: "Stop struggling! I'm just taking you to the higher deck so you don't get too sick."

Izuku kept quiet for the rest of the walk.

When they arrived they were 5 floors higher up than where the rest of the class and the pool where.

Izuku: "Ahh~ this so nice," He said after he was sat down on his own legs.

Katsuki was just standing a little bit away, admiring his Crush. Yes, Crush. He's had this crush since kindergarten, but he mistook the feelings for hatred (Somehow). But when he got into UA he heads talk about it with Kirishima and he found out that it was actually a Crush.

Suddenly Izuku hunched over and put his hand to his mouth.

Katsuki: "De-Izuku!"

Katsuki knew that they were no toilets near so all he could do was hug Izuku and rub circles on his back and hope for the seasickness to go away.

When it went away after some time, they just sat there on the ground, hugging

Izuku: "You... You called me Izuku"

Katsuki blushed

Katsuki: "Ye-yeah. What of it?"

Izuku: "Why?"

Katsuki: "B-because... Because I like you... Go ahead and laugh if you want... And, I'm sorry for how I treated you in middle school. I mistook my feeling for Hate and when I got confused I took it out on you" he looked away

Izuku: "Kacchan..." he began crying

Katsuki: "What? D-did I do something wrong?"

Izuku: "No. No, you didn't"

Katsuki: "Then why are you crying?"

Izuku: "because I'm happy! I'm happy that Kacchan shares my feelings!"

Katsuki: "Wha-" he was cut off by Izuku putting his on Katsuki's.

Katsuki was shocked, to say the least. He never thought that his Crush would share his feeling, let alone that he would be exposed because of Izuku's seasickness.

Then suddenly they heard shouting from one of the decks below them. Specifically; the one where the pool was.

They went over and looked over the railing, seeing almost all of their classmates panicking shouting about where someone where.

Izuku: "Hey Guys! What's all the fuzz about!?" He shouted down and everyone looked up at him and Katsuki

Ochaco: "Thank God! we didn't know where you guys were so we just assumed that something bad happened" She shouted back

Izuku: "We're coming down now!" he said as he took Katsuki's hand and went down the stairs.

The rest of the trip was just fun and games with some flirting between Katsuki and Izuku. Mainly Katsuki being the one flirting.
