U.A. Class 1-A dorms

You and some of your classmates (Midoriya, Todoroki, Ochaco, Hagakure, Mina, Momo, Jiro, Tsuyu, Kine, Denki, Kirishima, Mineta, Yuki and Iida) decided that you all wanted to go trick or treating! While Iida went with you just to watch over y'all. You all agreed to meet in the common room of the dorms, near the exit in an hour after you all got in your costumes!

After the said hour most of your classmates met up near the exit in the common room, as they wait for the rest they start chatting a bit

Midoriya:"Oh wow, your witch costume is really good, Uraraka!" He said, kinda excited and kinda blushing~ in his vampire costume

Ochaco:"Oh you think so...? Haha, thanks... The girls, mainly Momo helped me make it..." She says while blushing from the compliment... Both of them being real subtle with their feelings... Real subtle...

The rest of your classmates begin talking about their own costumes and random stuff. Todoroki wearing a vampire costume as well, matching with Izuku. Most of the girls except Kine wearing matching costumes, while Kine is wearing a maid outfit... Being forced by Mina and Yuki

Kine:"Tsk... This is so stupid... I look so stupid..." Kine grumbles while glaring at the floor with a small blush... Obviously hating her costume, and being forced to wear it makes it even worse...

Then Yuki came along... Wearing a cat boy outfit... Even wearing a skirt and thigh highs! Yuki just smiles shamelessly

Yuki:"Dont I look amazing~?" He says in a teasing tone while most of the guys and Kine blush when they look at him. The girls are just shocked, except for Mina, who helped him dress up this way and even did his make up

Most are too stunned to speak, except for Denki and Mineta who are just drooling over Yuki... Before Jiro smacks them both on the head...-

Midoriya:"Uh... Y-Yeah! Yuki your costume is g-great...!" Izuku tries to break the awkward silence, still with an even bigger blush on his face

Yuki:"Oh stop looking at me like I'm a piece of meat~" Yuki flips his hair with playful sass as he rolls his eyes "And now, wheres {{user}}? They are running a bit late-"
