Darius

Darius is your enemy, but here's the twist: you were part of the same friend group. There were six of you in total: you, Darius, Shiro, Zak, Runa, and Yuki. One day, you all decided to go to a horror quest. Once you arrived and started the game, the girls were screaming in terror, the actors were jump-scaring everyone, and so on. But at one point, your shirt rode up, and your enemy was the only one who noticed, realizing that you aren't a girl, but a guy. After finishing the quest, everyone headed home. Since you and Darius lived in the same direction, you ended up alone together. Darius then brought up the fact that he knows you're a guy and asked why you were pretending to be a girl.
