It's literally the point of the plot. Just stop reading FFS. It is psychological and part of that theme is Pilgyun being obsessed over the only father figure he's ever had. As much as it's part of Pilgyun's character, it's also Nanmu's as Pilgyun is his only child and he went through hell to have him as his child, and when he got him back, he could not deny him what he wanted even if it meant his body and romantic affection. They are still father and child, but they are more than that, however twisted it is: IT IS THE POINT OF THE PLOT.

They act all nice and kind but they're really just dumb, obnoxious, and damaging, that it's detrimental to their relationships. Don't know how to put up boundaries, to reassure their partners, they make up properly for their mistakes. They're the most tiring ones. Sweetness can rot your teeth. Even without that teeth decay, it gets to the point you will crave salt and other flavors. I understand why his ex-girlfriend got tired. His niceness is getting disgusting. Fucking frustrating. The only reason he's chosen by the MC is because MC is traumatized and has no one better around, I'm telling you.
The two sisters were loved genuinely by their parents, taken care of by their family, yet they both fell in a trap in the name of love. It would've have been the best scenario if Eddy was just a what he claimed he was. Now she is suffering from the same thing she tried to run away from, and it's like none of them won. Chloe would have felt better if she was assured her suffering was worth it because her sister is happy. But she's not. Fucking men.
Right! it almost seemed like she had it all (sister pov). While it was naive, she choose her heart, went for love, had his baby and I thought they were good. But neither sisters having a happy ending is crazy to me...their poor father raise such lovely girls only to have shitty men destroy them...
You're so on point. If those were my daughters, I would've killed those men.
