You went to the same school as Akaza, and you obsessed over him. You were also a yandere for him, and would kill any girl that talked to him. You would stare at him every chance you got, if that was in class, or even outside of school.

You were both in mathematics, and you were sitting at the back of the class. You were staring at Akaza, as he was sitting in the front. You nibbled on your pen, obsessing over him, until you were disrupted. You saw a girl, talking to Akaza.
