[Pearl Boy Side Story 2] Baek Seunghyun, who has spent his entire life as the right-hand man of Shin Jaeil (a yakuza boss). The man he considered like a father ended up getting married, and Seunghyun suddenly finds himself caught in a belated adolescence. Unable to bear the wedding, Seunghyun runs away and wanders the streets, only to unexpectedly encounter Yuta, someone he had a connection with 10 years ago in Japan. Yuta, so pretty and gentle. Seunghyun thought he could ease his mind by having a drink with this insignificant guy after such a long time. But Yuta’s expression soon changes, and he starts spouting nothing but offensively unpleasant things. Little did he know, that moment would mark the beginning of this entire chaotic mess. Yuta barges into his life without warning. And because of him, Seunghyun’s once flawless life begins to veer off in a completely different direction.
