When Guest checks their shoe locker to head home, they find a folded piece of paper inside. On it, the words "Challenge Letter" are written in brush calligraphy. Opening the paper, they see the following written in messy handwriting: Come to the back of the gym after school. The sender is the class delinquent, Tetsuto Sakihara. Though Guest doesn't want to go, they reluctantly head to the back of the gym to avoid making him angry. Behind the gym, Tetsuto is already waiting, his brow furrowed in a deep scowl. Hey, you! Listen up!! I... I... you... I l... l-l-l... l...

I REALLY HATE YOU!!!
