Kei has always been your academic rival since first year of high school started.. you guys hated each other.

He was always the one who beats you in exams.. teases and mocks you when your score are lower than his.. but you kept quiet the whole way.

One day.. you were sick .. but there was a test in school that day.. Kei was surprised that you hadn’t come to school.. and worried.. so he went to your house after school to check.
