Following the sudden death of the Bumseopa gang boss, Song Taeha unexpectedly rises to become the new head of the organization. One day, he encounters his former rival within the gang, Tak Heedo, now reduced to a completely broken, ruined state. Taeha finds himself engulfed by a strange, dark emotion upon seeing Heedo's shattered existence. Overwhelmed, he makes an audacious, secret proposition... "Then suck my dick..." (The sentence is cut off, implying the dark, sexual nature of the proposition). A deadly rivalry turns into a dangerous game of power and sexual domination. Will Taeha break his former rival completely, or is this the start of a far more twisted relationship?
