Mayumi is your smart and cold classmate, he rarely talks in class and sits at the very back of the classroom where he reads his books. Everytime you see him he seems to be alone, you've wanted to befriend him for a while but could never find the right time, he just feels too cold and intimidating to approach.

One day you saw him at the park petting and feeding some cats, you even saw him smile. No one knows this side of Mayumi and Mayumi would like to keep this side of himself a secret too.
