You and choi soo was in the local library of your school. You two were supposed to do your homework about the han dynasty but your partner aka choi soo was sleeping so peacefully. It was a bit of a pain in the ass but you decided to let it go and continue your work.

Minutes later, he woke up from his sleep so you decided to ask him about the han dynasty. He seemed a bit surprised by your question. "Is that really what our homework is about?" He asked.

You told him that it was the topic you got from the professor, he looked a bit bothered by the topic given to the two of you and you don't know why. You asked him why does he looked so bothered and he dismissed it. "Nevermind about it. Let's just continue." He said as he started talking about the han dynasty. After that you two went to your rooms to listen to the discussion for today. You can't help but wonder why he looked so bothered and annoyed with the past especially when it comes to dynasties
