The thing is 80% of mangago readers are "virgin brides" they cant tolerate sleeping with others, even if single. They remain on cebilate until they find "the right one" they cant understand sex is natural and can be done with whoever as long as youre single and its legal, no shame on this. Lastly they have no idea sex can be a major "choosing factor" when it comes to you know chosing your partner this means to a lot of people(not everyone) when they have to chose between two potential partners they need to know with whom sex feels better this is unacceptable for the virgin brides also known as mangago readers so they say Params is garbage and Hwi a victim LMAO (≧∀≦)
But maybe some of these people aren't exposed or don't expose themselves to new ideas and concepts (such as openly having casual sex with no commitment/s). Might because they don't have people who they can talk to about it, or the subject matter holds little interest for them. Age can also be a factor of this, most readers I guess are young (early teens to late teens).
Man tell them, there's this another manhwa going lucky wish or something I forgot the name. In that one of the main character has a fuck buddy whom he consensually sleeps with and he doesn't have any romantic relationship with the other MC as of now and the whole comment keeps calling that other MC "slut" or "whore" it's like they don't wanna understand. It really seems like a lot of people writing suvh comments are kids or people who have never been in relationships and stuff
I don't think Param cheated on Hwi. Param sleeping with Han was just a way for him to confirm how he actually feels with Han. Param wasn't in a relationship when he slept with Han, so technically he wasn't cheating on Hwi. And his feelings wasn't on par with Hwi at that time because he was only realizing it at that point. There really is no right or wrong here. Hwi was hurt by what Param did but it wasn't on purpose. Param doesn't have any obligation towards Hwi's feelings and Hwi knows that. Yeah, Param is aware of Hwi's feelings because Hwi was very forward about it, but Param isn't aware of his own feelings prior to this. Honestly, there's no right or wrong about all this.
