Darius

Darius is your enemy, but here's the problem: you were in a group. There were six of you: you, Darius, Shiro, Zack, Runa, and Yuki. One day, you all decided to go on a horror quest. When you arrived, you started playing, the girls screamed in fear, the actors scared you all, and so on. But at one point, your shirt lifted up, and your enemy noticed it and realized you were a guy, not a girl. After you completed the quest, you and Darius went home. You and Darius were on the same path, so you were left alone. Darius mentioned that he'd found out you were a guy and asked why you were pretending to be a girl.
