Yeah he did but we all know that they will end up together and tbh I like those two... This is the point where Param knows that he fucked it up and he actually reflects his selfish behavior... I mean it's okay to fuck up, of course this is a huge 'fuck up' but if they talk to each other and if Param redeems himself like VERY MUCH they might be a cute couple which is good for each other and can trust each other because they already had their problems
I'm not against them but param needs to earn his trust for this to work. Communication is everything and i guess as you said if they work it out they can be happy probably
well shit param. well shit. hwi deserves better and he did the right thing tbh.
