This is not a good justification for kidnapping and rape, Donghyun never forced Sungho to do anything, Sungho offering his body every time due to "fear" of losing Donghyun and then blame him after years is pathetic and makes 0 sense.
Just because you got your heart broken you don't go around kidnapping and raping people cause you are committing a crime, everyone goes through heart break he could've gotten over it. The plot itself is cliche and makes no sense at all.
I think you meant sungho is a criminal he is one who kidnapped and raped Donghyun lol
Right so you are saying that rumours which aren't even facts, rejection and death of someone's parents is a good excuse to kidnap and rape someone because you got obsessed over them, what the actual fuck, he found it hard to overcome Donghyun disappearance on him because on his head they were meant to be, we both know the world don't work like that, we can't stop people from leaving, we can't blame them for not remembering things that perhaps meant nothing to them and it is not by torture that you will get them to love you back he figured that out way too late.
You can't blame someone for your own mistakes, Sungho could have dealt with this shit in a more civilised way and I never said he should have repressed his emotions I just said that he had no excuse or reasons to commit crimes and NO he didn't go through half the pain, cause he might have been bullied but he caused a trauma on another person just because things didn't go the way he wanted.

I really thought Donghyun did something extremely terrible to warrant the anger Sungho has for him but it turns out he didn't even do anything really bad. He was just a kid who felt happy when he was seeked out by Sungho because no one else cared about him. He wasn't even the one who ended their relationship, it was Sungho. How was Sungho's pain equal to Donghyun? Sungho, as sad as his heart getting broken may be, has parents who loved him and he was well off. His only problem is he got his heart broken by Donghyun. Meanwhile, Donghyun lived a terrible life already without Sungho making it worse. He was poor, he suffered abuse from his uncle, he doesn't have a stable job nor a permanent home. And to add to that, he was kidnapped and raped and drugged. I feel really bad for Donghyun. I don't, however, feel any sympathy for Sungho.
