I’ve read a lot of opinions about Dalmi always being the mean one to Injae and how it’s annoying and nonsensical but while I agree that it’s annoying and I wish she would cut it off I kinda get it and have some sympathy for her. I was in a similar situation (parents reversed) when my parents got divorced but both me and my sister left with mom, and if my older sister would have told me what Injae told Dalmi when she left, spoke ill of mom, then went with dad and cut off contact completely with me saying I wasn’t her sister anymore, I would have ended up hating her a lot. Because that’s what happens when people you love deeply hurt you. You resent them and feel bitter and end up being mean and petty to them. It’s not nice but I think it’s human, so I get it, and I feel like it makes sense for Dalmi to act that way. I still have hope that they could make up eventually.
