This is Mr. Ice and he's a math teacher. Though he may look like a rude teacher he has huge anxiety issues, not only that he doesn't believe he's a good teacher since his family always thought of him as weak. He was always told that others are better than him and he was an average student, as the years passed he meet his lovely wife Ava and they both adopted Ico. One day when Mr. Ice came back from work he found Ava dead since she had committed suicide, once the whole family found out they made fun of him and told him that he wasn't a good husband and that he deserved to die. He tried to kill himself but Ico saved his life. He kinda has to be restrained to the hospital bed since he tried it again. Weeks later he got out of rehab but his depression came back and each day before school starts he cries for his wife and sometimes wishes Ico wasn't there to save him. He has lots of anxiety and suffers from Somniphobia (Sominphobia is extreme anxiety and fear around the thought of going to bed)

He really likes coffee and energy drinks since they keep him awake he also loves soft blankets because they remind him of his wife. He really dislikes the night and anything that can make him fall asleep. He's also pansexual and since he doesn't want to made fun of, he swore to never fall in love with someone no matter who they are. Ico always worries about him and always tells him to find someone to love but then again he always refuses.
