Locking away his past in the States, Min Sehyuk enrolls in Hanhwa University, South Korea.

An attempt to defend the weak lands him squarely in the crosshairs of the bully, Kang Kihyun. Sehyuk retaliates each punch with an unsettling response- a brazen smile and a taunting challenge to unleash a stronger attack.

Kihyun has broken countless spirits, reduced faces to tear-streaked masks. Yet, Min Sehyuk revels in the punishment? The bully vows to unravel the enigma of Sehyuk's unwavering grin and will not rest until he extinguishes the infuriating light radiating from the newcomer's face.

Who will be the first one to surrender and give in? A boy plagued with specks of his past or the one living in the embers of violence.
