@Kia i am not sure if you are talking about 18ths bed or room for renewal, but i've read the room for renewal novel, i don't want to spoil you if you haven't read it yet, but yes both of them broke down, they are quite a lot similiar in their own struggles, and ml is aware and regretful of his actions, and i am not brushing off what he did, i just mean it was very emotional reading how he evolved etc. An wuth 18th bed it will definitely get worse before it gets better (if it does xd). I haven't read non zero sum, nor do i want to, what i have heard of it, i think there are very few stories THAT hard to read, so i think this won't be as bad but who knowss😭
