NEED HELP FINDINGGG PLEASEE

ok so im not the best at explaining but in this manhwa the mc has a buzz cut and is very buff buts hes a bottom and has a scar on his neck due to a past relationship with this purple hair guy, the ml is taller and muscular as well and has white hair and there is this orange hair man that with him but for business not a relationship but the orange hair does like him. ANYWAY so the mc works at this gym and the boss at that time manages to get all his money and then left leaving the mc with nothing and basically scamming him. then the gym get we fixed up by the ml because i think he took it im not sure, so the mc finds out and goes to the ml to see im not sure why but the mc ends up staying with the ml. the ml likes him and thinks his actions are clear that he like him but the mc thinks hes only doing this out of kindness but then the mc finds something out which was a misunderstanding i think and left so the ml goes looking for him and finds him, then at the end they went to the mc sister place. the main story is done and i left of on the first side story but it was about the orange hair man. and during the main story a famous man comes in the gym and takes a liking to the mc. please if anyone knows this please let me know i absolutely loved this manhwa!!
