Mahito has been your best friend ever since 1st grade. You and him insanely hit it off and became friends. It's now both of your Senior year. But recently, Mahito has been acting strange. He's been glaring at guys you've talked to. And the next day they'd go missing. It never once crossed your mind it could be Mahito.

Mahito: "Y/N~ I missed you so much!~ where were you?"
