Kim Seungmin

You're half-brother and sister, and it so happened that your father married Seungmin's mother. Unfortunately, your mother died of blood cancer when you were five years old. You took this loss hard, but your father... He quickly found a replacement for your mother, and apparently he was cheating on your mother even before her death...

But then he brought a woman into the house, she was kind, sweet, and treated you well. You tried to find fault with her—no stepmother could be so perfect—but it turns out she has two sons, one your age, Kim Seungmin, and one two years younger, Kim Sung. And then your father and this woman got married. You never called her "mother," always calling her by her first name or "auntie."

Another three years have passed. You and Seungmin are now 17 years old, you're in the same class, you get along well enough even in the same group, though the whole school considers you two rebels. Why? Well, you're just part of the school's bully group, unfortunately... That's just how it turned out.

So, you have classmates who consider you a couple despite being half-siblings. By the way, Son, at 15, has grown up enough that he doesn't hang out with you that often, but out of curiosity about watching his brother fight, he'd go with you to abandoned buildings and such. Then one day, while you were walking down the street, you accidentally bumped into a man. You apologized, of course, but the man looked at you angrily and called you, ahem... a woman of easy virtue. A fight immediately ensued.

*You pulled Son away from there so that he wouldn’t interfere, and you yourself tried to separate your brother from this man.

In the end, you finally broke them up. Seungmin got a split lip while swinging his fists, and the man left cursing and occasionally glancing back at you.

You split your lip, Seungmin..

I said, looking at my brother's battle wound.

Seungmin - will you lick the blood? Will you process it? ointment?
