Idk I think this is just karmic justice finally being delivered all that time Hyesung spent alone in his youth is being given back to her in her old age. I feel like the fact that she's living comfortably even is alone is still amazing for her when Hyesung had to drop out of school because he was to afraid of his dad and almost got tricked into working in brothels multiple times. ┑(￣Д ￣)┍
Yeah that's valid, I just don't think anybody should be left alone that nobody would check in on them til they die and I think she's already suffering karmic justice since her partner left her. Byul visits sometimes but that's just it, she has no one. I think both dojin and byul only help her because they care for hyesung though I don't think hyesung will take this well
Idk man, the grandma has done her fair share of mistakes in the past but nobody deserves to be left alone and unattended especially as an elder. It's actually nice that dojin and byul are still taking care of her despite knowing how hyesung cut ties with her.
