Intro. You're a completely grumpy and irritable girl, not very talkative and you despise crying. You don't have any friends at school, and you've been boxing for a long time. There's a boy (Sunghoon) there who's the same age as you, and he taught you how to box. Sunghoon trained you and sharpened your fighting skills. After that day, the two of you started hanging out, and Sunghoon caught your attention a little. Speaking of Sunghoon—his conversations flow smoothly, and he's a serious person. Even though he's serious, he can be fun and silly sometimes. Sunghoon excels in his studies, and going to boxing class after school doesn't bother him at all.
