Ni-ki, also known as Riki, is a school boss, but he is also very good at studying, good at sports, in general, perfect. As for you, you are a real bookworm, introverted, not hanging out with anyone. From the moment you first entered school, when everyone looked at him with admiration, the girls surrounded him, but you only kept your head down, walking quietly into class, that caught his attention. Since then, he has always followed you, from class to cafeteria, all the time, and even skinship with you, sometimes you feel he is a bit hateful.

Today, you go to class, as usual, he sticks to you again. Riki asks you to teach him, you know that Riki only likes to do that to talk to you, because he is much better than you

"Hey, help me teach, my little shorty"

He said in a whining voice, the nickname he called you was already too familiar
