It's too soon to make a judgement. But I like the story currently. It's really interesting. So, what if she was bad in her previous life? She's trying to change. Although, I would've preferred if she stopped grey hair from abusing the green hair. She was already humiliated enough. She didn't deserve that much.

It was sexy as hell but uncomfortable too. There was no need for the whole minority abuse thing if they weren't going to expand on it. It's hella uncomfortable to read them especially when the world is currently having several minorities rise up and release information about how they're being abused in their countries. :(

Why are the twins calling the red hair 'father'? Who is he? Who is the Schulz family?

But now we have to question if he even likes his wife. As you said he's two-faced and he did say that him hating the Lombardi was a secret among the Schulz men meaning his wife doesn't know. Maybe he hates her but sucks up to her since marrying her gave him power and status that he didn't have before. Anyways, the wife deserves someone better imo :(
Why is Jaeyi feeling bad about wanting to be sexually free? She did it. She didn't fool anyone or trap anyone in a one-sided relationship. Later, she cut it off when she fell in love.
The only wrong thing she is doing is beating herself up over it. :/
Stigma. Normally, Koreans are conservative and Bogeum is part of the conservative party. So Jaeyi being part of the other side feels guilty about it. But for all she knows Bogeum may be chill about it.
