Totally agree. It’s surprising that they even dedicated so much time to the mother subplot as I was expecting it to be nonexistent since this story is a 180 in tone compared to love is an illusion. Yes I hope we can revisit and flush this out more with the parents later but as of right now, the lighter tone just doesn’t suit that heavier topic especially so early on.
but then again if fargo didn't want it to be serious she shouldn't have used hyesungs trauma to set up a kissing scene for byul. she could've went any other route to reach that. a lot of her readers share contempt for hyesungs mother and the fact that it was brushed off because apparently "hyesung didn't want byul in the first place (unplanned pregnancy)", "she birthed you", "she looked like you" is insane. that man had to face the threat sexual assault as a child and those are the "reasons' his family think she should forgive his awful mother? fargo needed to think this through a bit more

I think too mmay people expected something more serious. I really don't get that vibe from this story (especially compared to the original). I don't know why people expected Hyesung to leave Dojin. They been married for almost 20 yrs. He's not going anywhere. Although I am glad that Hyesung hasn't forgiven his mother yet.
