He was jealous of Jae Moon since they were young, that's why he decided to follow his parents career path so that he will gain their affection. But then it resulted from him being SAed and he was out of it to know that was Secretary Kang. Anyway, that was a wake up call for him to follow his own path (as a perfumer) and search his saviour. He can't just do that bec he is afraid to disappoint his parents and since he is jealous of Jae Moon, he used him as a tool (by false accusing him) so that he can step away and do his own thing without making him look like a sore loser and disappointing his parents. This is also his indirect message to JaeMoon that he has hidden anger towards hin all this time and Jae Moon just accepted it. Im sorry I don't think I conveyed it well, but I hope this helps a little
