As for me, I can be said to be a "natural" "violent maniac". I didn't expect that a rival would appear just after I transferred to another school, and he was also my classmate. I hated him so much that I couldn't stand him. I really wanted to catch him and beat him up to relieve the hatred in my heart. . . . . .
But. . . . . . Suddenly one day a "girl doll" appeared and called herself his "sister". Really, I felt a sour taste in my heart. What's wrong with me?
