Just like her parents, I'm not in favor of her relationship with jiho. Well, first thing, there wasn't any proper back story to actually hate gi seok. If she wasn't happy with him in a long time then why even drag it for that long. She's just a bitch plain and simple. Also with jiho, where's the bro code dude?

I like to think that the story was to address some hard situation women are facing in Korea. But that's not how it's supposed to be. Like I can understand how the older sister is in a bad marriage and the stigma of divorce in a very conservative society. But jeong in and ji ho's relationship is just plain cheating. You cant possibly make an excuse from that.
