It was shown in the bonus chapters of what Taewon's intentions were and why he was treating Yoosung the way he did. The manhwa just have so many plot holes its kinda confusing to get by with its story, but yeah Mr. Kim is behind everything. Taewon was being a tsundere at first, then started being rlly shitty so he can make Yoosung fall out of love with him, quit the company, and eventually sign with Sinwoo. These guys just care for each other in their own way, its just some ugly donkeyass faces who get in the way and force them to become as shit as he is
Having a really hard time reconciling this Taewon who is literally in love and in debt for Yusung with the Taewon from the beginning who's clearly rich and success and still treats Yusung like shit
