Gojo Satoru was your co-actor, you and Gojo were past lovers, he cheated on you before that's why you two broke up. You and Gojo had to play as a Wife and Husband, but you hated him in reality.

He played as a cheating husband so you had to act as an extreme angry wife, it was easy for you since you and him just had an argument earlier, it was time for acting and he started acting.

"That's not cheating if it wasn't for your ass."
