Thank you for the spoiler. Saw the raws too, but was waiting for someone to write on it so we could discuss. Although I get your point, Hwi already knows something happened between Param and Han. And although Param never really came out and spelled it out to him in full, he's probably figured it out. That was why in chapter 43 he told Param he knew Param always had feelings for Han. I think it will come as a gut punch for him to hear it in full detail from Han, but seeing that Param has asked for another chance, told Hwi that he messed up, got on one knee to plead for him, I think Hwi will be like "fuck you Han, I already know". Or at least I hope so.
yeah, considering he already figured out something happened I think what probably gonna hurt him would be hearing it from Han and not from Param himself. Hwi here is the more mature one, he already knows something fishy with Han, so I hope he won’t get too touched by his words. The most positive outcome form this situation could be Hwi don’t giving a fuck about what Han will say, then tell Param about this so that Param can figure out what a shit Han is and decide to finally go and send him to hell. But I still don’t trust Param judgment so -
Hwi know something happened but not the whole truth. Param is all over the place and getting asking for a second chance isn’t enough. His actions need to show his feelings are genuine and they haven’t. Param went from sick with guilt, to all giddy for Hwi, then questioning everything and crying after phone sex. He’s sending real mixed messages here.
I don't disagree with any of your points. Hwi knows something happened, but not exactly what happened because Param never told him the whole truth. Having to now hear it from Han I'm sure will come as a gut punch to him, and it will definitely hurt. And Param is kind of all over the place with his emotions right now, its really frustrating. Like grow up, talk to Hwi. That's what I want them to do more than anything, talk, come to a real understanding of each other, express your true feelings in no uncertain terms. There's just too much uncertainty and angst right now. Ugh!!!

so Hwi and Param finish their sex call, then Param tells Hwi that it wasn’t the reason why he called him, Hwi understand it’s time for both of them to meet and talk about their relationship. Param struggles cause he keeps being horny but want to show Hwi that he doesn’t like him just for the sex (honestly Param really needs to take a grab on himself cause I get his horniness but if he cares about Hwi fr he needs to develop). The chapter ends with Hwi going out from the building and Han is there waiting for him .... so they gonna talk (I have an awful feeling about this, Han gonna mess up everything as usual, don’t be surprised if he’s gonna tell Hwi he had sex with Param)
