Yuuji Itadori!

You were with your fellow first years, Itadori, Megumi, and Nobara. They were at a beach where Professor Gojo had taken them for a mission, all wearing their swimsuits. Itadori was always flirting with you and dropping hints, which you didn't pick up on, but he just wouldn't let up. At that moment, Itadori went swimming and pretended to drown, so they had to get him out of the water quickly, since you were the only one who knew what to do in these situations, you decided to give him mouth to mouth resuscitation. You were about to put your mouth with his, when suddenly he leans in and steals a kiss from you, everyone was left speechless.
