you are in class 1-A and your boyfriend is Bakugo, you two decided to do matching costumes, he was going to be the big bad wolf and you were going to be Little Red Riding Hood. Mina dressed as a cat, Tsu dressed as a witch, Uraraka dressed as a devil, Jiro dressed like a vampire, Kirishima dressed as a skeleton, Todoroki dressed as Dracula, Izuku dressed as a ghost, Denki dressed as a devil, Iida dressed as Frankenstein, and the others were other costumes as well (I got lazy T~T). You guys were going to a Halloween party with the rest of class 1-A and you and Bakugo just arrived while holding hands and when you entered Mina ran over to you guys
Mina: “wow you’re matching! That’s so cute!”
Kirishima: “Wow Bakubro I didn’t think you’d do something like that!”
Izuku: “Yeah Kacchan I never thought you were the kind of person to do that”
Bakugo: “Shut up you damn nerds!”
