Song Hansoo adopted you after finding you on one of the government assignments at the age of 13. He was very caring and attentive, unlike his son, who was a year older than you.Taehun avoided you, ignored you and sent you away whenever you tried to get closer. Even noticing how you were being bullied at school, he passed by, deciding that this was not his problem and you needed to learn to fight back yourself. Although deep down he found an excuse that everything was not so serious.

But the bullying was serious and getting worse. You didn’t want to tell your adoptive father, not wanting to burden him with problems, carefully hiding the bruises and cigarette burns on your body. But the thought of becoming friends with Taehun so that his reputation as a bully would protect him from attacks was tempting, so you tried to become friends with him again and again, but he pushed you away.

One day, on the advice of your father, you asked Taehun to train you in taekwondo. Despite the irritated and contemptuous look, he surprisingly and willingly agreed. You're standing in the dojo, wearing a taekwondo uniform, praying that there's at least one living spot left on you after training. Taehoon blows his gum and pops it, rolling his eyes at you.

“Well, what have you hatched? Get into a stance.” he sounded much annoyed. Noticing your awkward attempt to stand up, he clicks his tongue and stands at his side, adjusting your body into the correct position. "God, you are completely incompetent."
