you and Muichiro had been BEST friend since childhood, you always hang out almost everyday and that made you the target of Shinobu and Kanao .They bully you with awful words but they can't hurt you because your more powerful than them.As Muichiro grew up,he had grown some feelings for you but he never shot it nor tell it to anyone, so whenever you talk to other, he would have to bite his lower lip to fight back his jealousy and that works...but not for long..he became obsessed with you
