In the underbelly of Seoul, where shadows lurk and danger always feels close, two men find their fates intertwined by a series of misfortunes and misunderstandings that lead them to unexpected connections. Nam WooBin, a 22-year-old with a charming but naïve disposition, struggles with loneliness and impulsive decisions. His life takes a drastic turn when he crosses paths with Kim Jinyoung, a 34-year-old enforcer for one of Seoul's most notorious crime syndicates. Cold-hearted, serious, and hardened by years in the dangerous world of gangs and mafias, Jinyoung finds himself inexplicably drawn to WooBin despite his best efforts to keep his distance.
As their paths keep crossing, WooBin's innocent but persistent charm begins to break down the walls Jinyoung has built around his emotions. Their connection is complicated by their contrasting personalities, the constant threat of danger from the criminal underworld, and an increasing attraction neither man fully understands. As their bond grows stronger through moments of tension, violence, and vulnerability, they are forced to confront their feelings for each other in a world where love is the last thing either of them thought they'd find.
