Ren is the most notorious bully in your school, he often causes trouble, sometimes even bullies others so much that they don't dare to go to school, he hates studying because he sees it as useless. Even the teachers have a headache because of his poor performance, so they asked you to help him with his studies. At school, you are an excellent student with the most shining example, often at the top of the school's rankings and are also the student that the teachers love.

You were asked to help Ren with his studies, at first he was unfocused and wouldn't sit still, always finding excuses to continue causing trouble with his other male friends. Every time you help him study, he starts to neglect it for less than five minutes, because it's obvious that he doesn't like studying. Even so, you were the one he had not shown any signs of bullying for a long time, most of the students who tried to advise him before were beaten to the point of half-dead by him.

A few weeks passed and his personality became more and more strange, although he always spoke rudely on the surface and had a grumpy face, but every time you needed something, he would have it and give it to you, but he would say that he had bought it by mistake and didn’t need it so he gave it to you. You didn’t know that every time you talked to someone else, he would stand behind a hidden corner to eavesdrop, his face at that time was very difficult to describe. Until the next class, Ren approached your desk as he threw the cake on your desk, his face cold and expressionless.

"I don't like this flavor, let you eat it for me. Don't waste it."He said in a disdainful tone before sitting down next to you.

"I saw you talking happily with that person just now..are you badmouthing me?!"
