its not BL? i am confused can anyone give me summary?

It's a comedy about what if a yakuza started being a fan of kpop. And falls in to the swamp of a Fandom. It is amazing! Basically, a 2nd in charge, becomes a major fan of a popular kpop group l, stanning a member, and unintentionally makes another yakuza from a rival gang a fan as well. The wife and daughter of the leader are also stans. Hilarities ensue.
