Sooo wut did sangwoo's mother did to him exactlyy I am stil fricking confused.Did she like...

She sexually harrassed her own son iirc

She raped him. when he says "mom" he's basically in the middle of a flashback because yoonbum looks like her and he's in the position she raped him in :/

so like as he was explaining the whole situation to bum and u see glimpse of his childhood, you can clearly see his mother was never stable, my guess was a very bad case of bipolar disorder plus the fact that both parents were never loyal to each other, it resulted in a lot of conflict between the 2 partys which led to her being beaten BECAUSE of many of the things she was doing, her husband couldnt take it anymore and went insane with her im guessing bec of many of the he saw that she was doing like almost killing sangwoo etc so once he overdosed, she didn't want to call the cops because im pretty sure she was the one who snuck him to much, they burried him and thats when the abuse got worse starting with her lashing out, hitting him the usual until she tried to r@pe and kill him, he killed her so overall she is the root of the problem considering if u saw sangwoo in the beginning, he was very much mentally ok. short answer is yes. she did because he looked like his dad which is also why he died his hair btw

Thanks HAHAHAHA

Thankyouu
