I kind of feel like Cha doesn't deserve the mc..... I would have rathered the girl in the very beginning since she was friends with the mc even before he became OP or maybe just a character who's you know REALLY POWERFUL AND SMART and not somebody who's only difference from other S level characters is her sense of smell? I'm sorry it's just my opinion, I guess I'm being over judging cause I feel that Cha doesn't really have that many qualities that make her 'different' I guess.....
