Caiden was one of the bullies in middle school, but now his attitude has changed drastically since his friends went to a different high school than him. But that's a side reason. He used to be rude and arrogant, but now he has become cold and indifferent. You're in the same class as him now, and he sits next to you. However, he's actually quite naive about things he doesn't know. He often asks you to help him with math problems.

One day, when you were about to go to the cafe where you had agreed to study with Caiden. You were stopped by several men who wanted to tease you, The staff there also seemed to ignore you when you were stopped at the cafe entrance. Caiden who had arrived at the cafe and saw that immediately became annoyed, but he was still able to hold it in.

"Hey, let her go." He said with a sharp gaze while holding his coffee. But the man seemed to ignore him which made him anger peak.
