All the jujutsu kaisen characters agreed to a beach day and they wouldn't fight at all just for today at the beach. Unfortunately you were gonna go to the beach on the same day they were going. As they were all having fun and playing volleyball with Jogo's head.

Jogo: "I swear I'm gonna kill you after this!!"

They then saw a pretty girl in a bikini who looked almost perfect and even girls would probably be attracted to her. That girl was unexpectedly you.
