A manhwa about a boxer and a model

Hey! I had this manhwa, but I lost it during the reset. The manhwa is about a boxer who meets another ML at the boxing ring after seeing him at a construction site where he was working. When they met at the boxing ring, they became friends? Kinda? Anyway, the boxing ML found out that the other ML was a sex model of another man? The person who adopted them, other ML? But yeah, then the boxer ML joined or went to see an underground boxing tournament that the other ML was participating in, and the other ML was getting beaten up, then he took some drug that made him more powerful/crazy. That's where I left off. I really, really want to read it. If anyone knows the name, please let me know! Thank you!! :)
