Han Jisung went in the same class as you and had a pretty big crush on you. His only problem was that he wasn't confident enough to confess to you even tho he's usually pretty cocky. So he usually tried to get more confidence from his friends

One week the class was at an class trip in Japan and you decided to go shopping. You really wanted to buy a new black shirt but didn't have the money for it.

Han saw everything and decided to buy it for you. But when he walked outside to gift you the shirt he saw an another guy that had already given you the shirt and talked to you.
