If I had to guess, mr Yoon, the „friend“ does not want anyone else to hear what he wants to discuss with him. I‘m strongly suspecting he‘s someone from the „real world“ who knew the MC, and wants to talk about it. So he can‘t exactly risk anyone hearing this
Hieonjin is seriously the only option of the 3 guys ╥﹏╥ Mujin may be softening, but he's still abusive and possessive as hell. And the "Friend" took his fucking phone and smashed it for no reason which is a whole mess of red flags.
