i don't remember who mr.Ha is but MC didn't call his manager because he was scared that if it was true it would hurt too much and also if it wasn't true his manager who stuck by him through all these rumors might be offended. So I'm pretty sure MC is gonna wait to gather more clues/evidence before he confronts his manager. Hope this helps!
male lead, blond actor man, the "fucking handsome" guy's name is
Ha Hyunjae
*Ha Hyunje

So guys I reread the chapter and also from some comments below, here’s what happened on the latest chapter (ch 19). MC saw a paper with something written about investment, which probably is related to the show MC was casted on. Then MC remembered that earlier (or in previous episodes), his protégé was talking about some investor, so MC meet up with him.
After he left, ML apparently was awake and was talking about paying back on a favor MC seemed to have done seven years ago.
Then, MC and his protégé was talking about the rumor and stuff as usual but the most important part of that scene was when the protégé pointed out that an investor of the show that intended to destroy MC’s career was actually on the set the same day MC encountered Reporter Kang from previous episode.
Initially, MC realised that “investor” was the manager of ML. However, he didn’t remember ML calling that guy his manager. He then realised that the person who actually made him think the “investor” was ML’s manager was actually MC’s manager (probably in earlier chapters but I couldn’t find it). So the last scene was MC contemplating to confront his manager, the “hyung”. I don’t get this part tho. I thought he wanted to call his own manager but he then inquired about Mr. Ha, which probably was ML. So yea.
