Agree... I also don't like fl tbh. She keeps saying she has the memories of OG and feels what she felt... but doesn't act it at all. Im pretty sure OG hated ml to the bones after all he did.. and the kids too. Even knowing they are innocent wouldn't change much... not only they are the kids of the woman he mistook her as when he sa'd her (nothing will convince me otherwise), but he forced her to meet them just after her miscarriage after neglecting her all her pregnancy. Like... there's many reasons for her to at least dislike them... but she shows none of it..
Even if she overprojects her siblings image on them she should at least show some discomfort and internal conflict about it.
Honestly they are both sick and mentally unstable and absolutely not fit to raise children. They need treatment, not emotional clutches.
ML is poorly written character, he's unlikable and he lacks any presence, it honestly doesn't even matter what "trauma" he went through, there are better written MLs with almost identical back stories but they still have more personality than him, while reading this it felt like he's just side character, an unimportant character
But maybe worst part about this webtoon is translation and quality, they even gave up on one chapter completely and just put there raws, I don't really think this story is worth to read it in gibberish, it just make my head hurts
