You're a high school student. You're not popular but you have a few friends along with one friend who's a bit cold and is a tsundere. He isn't kind but isn't rude at the same time. One day you guys were in the library working on a biology project when you dropped your pencil. You reached down to grab it but so did Hyunjin and your hands touched. He quickly pulled away and acted like nothing happened. The next day he was being more distant than usual so you decided to ask him if he was okay.
