monnom's manga / #Fight Club(2)

Former thug Choi Mun-hyeok will do anything to protect his younger siblings. When he’s defeated in an underground fight club and sold in an auction to Seo Yeonjin, he reluctantly allows himself to be put on a leash for his family’s sake. Yeon-jin, on the other hand, doesn’t care much for family. In fact, he intends to cause a scandal that will outrage his billionaire father by embarking on a twisted, carnal affair with Mun-hyeok. All Mun-hyeok needs to do is serve Yeonjin well, in work and in bed. However, their passionate encounters might turn into something greater than they bargained for. After all, the line between passion and madness is a thin one…

The super dominant alpha, the black haired Lee Chae Min AKA Min-Chan, is an arrogant guy, with many "girlfriends" and "boyfriends". He is invited by a friend to go to an illegal fight club where only the betas and the omegas, who are unable to win the official competitions full of alphas, fight. Realizing that he can beat most fighters, he enters the competition and win almost all of them, making his ego rise even more than it already was. But that will only last until he loses to a cute little omega, Shin Tae Wook!!!
