From ryColaa:

Reputation is everything in a world of icons and popularity contests. So why not score some points here and there by being the nice guy? This is the way Kang Shin-gi legitimizes the fake personality he has everyone believing. Armed with his above average looks and a (completely false) angel-like personality, he has every girl in school head over heels, and all the guys looking to him for guidance. With the exception of having a screwed up cross-dressing devil for a dad, Shin-gi’s life is absolute perfection (*cough* of lies), until one day, Um Seung-hui transfers to his school.

While being a complete martial artist freak, she also likes to fib just a little in front of those who know her… you know, like acting like she's just a scared little girl who'd play with kittens rather than break brick walls with her head!

Fate has brought these two masters of lies together, and the two must battle it out to see who will be crowned the undefeated heavy-weight champion of fakeness!
