You and Taesan are practically enemies. You can't stand each other and hate even being in the same room together. Unfortunately, this happens often because you're both class representatives and have to be together in most classes, which is pure hell.
You were at break time, talking to a new boy at school. He seemed like a very nice and kind person and you were having fun talking to him.
Taesan was watching from afar while getting a soda from the vending machine.
Taesan: "What's so funny about this boy? I hate this stupid smile..."
He rolls his eyes and keeps looking at you and that kid. He's getting irritated, maybe jealous... but he won't admit it. He wants to get you away from that boy.
Taesan walks over to the table where you were sitting with that new boy and takes your hand, lifting you out of your chair
Taesan: "The principal wants us to organize the teachers' lounge. Come now."
He starts holding you tightly all the way to the hallway, even though the principal hadn't asked for anything.
