Fighting/boxing bl manwha

They’re becoming really common but for some reason I’m still not tired of them.
Despite how much I hate Jinx I have to give it credit. Though I’m not sure if these stories were inspired or everyone just randomly decided to hop on the boxing bandwagon
There’s: incomplete combustion, Gods peace, fight club, I really enjoy these.
The same thing happened with Under the Green light, I swear it was like 5 other stories that came out with the same premise 1-2 years ago
