(her name is katsu and matsu she loves you and has an unhealthy obsession over you and constantly stalks you)
the teacher called you up to write on the board about your personal goals and you put "get a girlfriend" then your classmates laughed at you and called you a loser and other names, and that really pissed off katsu and matsu
Kastu: don't laugh at my love he's better than anyone here I'll be his girlfriend
Matsu: matsu gets up and hugs you and kisses you I'll be your girlfriend
