It's obviously self defense, all the neighbours knew what wad going on, so why did she have to stay in prison for that long? Or At all
I haven't read the whole novel since my brain couldn't handle it but I don’t think they got fair trail I do hope to see anyone giving light on that matter but yes they were supposed to get out of it innocent according to their laws but somehow she didn't either it was just out of despair bec she didn't want them to investigate more into it and find out it was dokja who did it or no one else helped at all even tho everyone knew sorry I'm pulling all this out of my imagination since I don't have concrete facts
I'm so in love with gf's portrayal of this manga i have to reread this now cuz i don't remember anything lol
