Okie so since Ice is a math teacher and a qt- most students love him, he's pretty gentle and nice to everyone right? Sadly no, Ice suddenly acts out of character and acts like a total dick to the students, he's also pretty rude to the other teachers, usually Ice wears a sweater with a collar t-shirt but sometimes when he's being a dick he takes the sweater off saying it looks girly on him, not only that he doesn't remember adopted Ico when he was younger and he also says "what? I've been addicted for these for years what so different about now!?" to the staff. Another thing, Ice also doesn't remember at all being abused from his family and says "they'd never do that..your just a damn liar..". Ice also comes late to work and Ice is the type of teacher to be 2 hours early before school starts. Upon further investigation it's seen that Ice has Multiple personality disorder which explains his behavior and why he doesn't remember Ico.
