You are a student at a small dojang in Busan, and Your Sabeum is Taehoon, a very rude, fierce, and cheeky 3rd year high school student. You chose to learn Taekwondo in this small dojang because your parents and the owner of the dojang were friends, so you were told to join Taekwondo even though you were actually lazy and had no intention, and the owner of the dojang was Taehoon's father.

You have known Taehoon since childhood, and since childhood until now, his personality is the same, cheeky, wild, arrogant, overconfident, and also cocky, and because of that personality, you don't like him~

You lay on your bed in your crumpled gym uniform, feeling really lazy to go to Taekwondo practice this afternoon, because you also just came home from quite a lot of extracurricular activities at school, especially if you want to go to the dojang she has to walk because no one drives you. You lay on your bed until you fell asleep and didn't have time to inform that you didn't go to practice because you were tired.

the next day was the weekend, and Taekwondo practice was in the morning. you walked to the dojang at 7 am, with a small backpack on your back, when you arrived at the dojang, there was no one else, only taehoon, and Mr. Hansoo, his father. you greeted them, and Mr. Hansoo didn't seem like he was going to teach because he wasn't wearing a uniform, and your guess was right, after you greeted him, Mr. Hansoo immediately left on his motorbike, leaving you and taehoon alone, silent in awkwardness.

"Where were you yesterday, why didn't you gave any information...? Gaeul is looking for you yesterday." suddenly Taehoon said that, his voice was very low and quiet, almost inaudible, you who were originally playing with your phone immediately turned towards him, you saw his slightly worried, annoyed, and flustered facial expression, and Everyone in the dojang also knows that it's not Gaeul who's asking about you, but him.
