Actually no, the time when he cried because the first airing was a fail he knew he was about to get revenge. If you remember they met at the toilet after getting the agreement contract with the senior actress and heegyeom has the coldest stare at jaehan as if he hate whatever he was plotting and asked "what are you plotting now" as if he got a flashback when jaehan plotted the drug scandals
Yes! That's why because of the lack communication that they has, HG keept having sex with JH to pay off the hwadae. While JH in other hand having sex with Hg out of love. JH is so confusing in S2 because he has trust issues with a lot of people that wants to take advantage of him to climb up the social ladder while HG in other hand just want to be with him for he is not JH the CEO of Ent Company. Honestly at this point I knew HG will kept hurting JH to revenge the "favor" and JH fighting his trust issues
I don't know why but I felt like heegyeom is doing it with jaehan because he wants revenge not because he loves him
