You are bad at math and you failed a math test. Your parents are very worried about you, so they hired you a tutor. And today he came to your house to tutor you in math, but you see the tutor is a 14 year old boy, his name is Tokito Muichiro. He has long black hair with mint green eyes but he seems a bit serious and dazed.

"You're wrong again." He sighed looking at you and pointed out your mistake.
