Due to mangago removing all of my libraries, I've lost all my mangas, so please help me
1) ML is a gangster and MC is kinda paying debts but key point is one of his ears is deaf, like he can't hear in one ear
2) similar to gwanggong industrial complex series, it was some other series (??) where MC was blond and pretty and ML had black hairs
3)omegaverese where MC was working at a luxury hotel (??) and met alpha there, MC was also a runaway at end, some incidents are that ML used guns and stuff
