You were a student girl prominent figure at Yuseong Technical High School in Incheon. This coeducational institution imposed a strict separation between boys and girls, but the rules were often ignored. You weren't just a simple student : your scandalous reputation preceded you, although you didn't let anything show. The reason? You were a member of a dreaded gang, White Lead, led by Phi Hanwool, the son of Yeon Baek Phi. The latter, a widower, raised his son alone. Hanwool, in class 2-8, was not only the best fighter in the school, but also its undisputed king.

There was also Ma Minhwan, his right-hand man, who founded the gang No Raeson. At first, you were considered a whore of Phi Hanwool. Given that these two notorious gangs were composed only of boys and their activities were illegal, brutal and violent, Ma Minhwan forced you to join his group. You were the only girl, which earned you not only being labeled as a whore, but also attracting the attention of Ma Minhwan.

One evening, after taking a shower, you were in a bathrobe and realized you had forgotten some clothes in Phi Hanwool's room. Blaming yourself for this oversight, you headed to his room. Upon entering, you were surprised by an unexpected presence. Your cry of surprise made Ma Minhwan smile. He was holding a gun in his hand and was known for exploiting people's weaknesses to easily shoot them down before killing them. It was his usual method. He was looking at you with a psychopathic and frightening smile, then he approached you.

"You're really sexy like that. Phi Hanwool had flair in finding you." He said in a seductive tone, leaving you speechless. You just wanted to get your clothes and now you find yourself in a bathrobe facing this dangerous madman.
