i think some actions (particularly what hes about to do next) should be held accountable by him and him alone. he has been a decent person while in school even with his mum being the same was he not? His obsession and refusal to accept rejection has been his own doing solely and what he thinks he’s owed for some deluded reason. We can only blame his mother to a certain extent
"particularly what hes about to do next" YOURE KILLING ME WITH THE FORESHADOWING but yeah youre right, at the end of the day, regardless of how he's been treated, his actions are his own choice, i guess ive read too many manhwas that have worse characters that seeing a character like seungwoon just triggers the "pity, you couldve been a good kid" to me

idk i feel more sympathy for seungwoon than hate, really. bro's not a good guy but frankly im more in favor of strangling his mother because we wouldnt have been in this icky situation if his mother wasnt so controlling
