Namjoon and Bang Chan

Namjoon is an alpha, 31 years old, with long blond hair, a mafia boss, an aristocrat. Kim Seokjin is his husband, 29, an omega. Namjoon loved Jin, but Jin didn't reciprocate and was with Joon only for money and influence.
Bang Chan is an omega, 29 years old, and works a low-paying job as a bartender. Chan also has a boyfriend, Changbin, 30, and an alpha. Changbin had a lover, Kim Seungmin, 26, and an omega. Seungmin lived in another country, and because of that, Changbin left and dumped Bang Chan.
Because of this, Bang Chan got depressed, and after that, he went and got so drunk he couldn't walk, at his bar, along with Yoongi, Jisung, Jeongin, Hyunjin, Hoseok, and Taehyung. But suddenly, Jeongin noticed two figures appearing in the doorway of the club, one about 181 cm tall, the other slightly smaller - 174 cm.
