Yeah.. same. I was facepalming the whole time. I assume she was thinking its like when kids say they want to marry their parents but it feels weird bc in webtoons the adoptive siblings can and do fall in love. It was odd of her to plant that idea in his head. I hope he grows up to realize they're siblings and doesnt become 2nd ML
I mean I guess this is just a matter of taste. I personally find it gross when the FL and ML are adopted siblings that spend their childhood together and are explicitly raised as siblings bc honestly the only thing that makes incest weird to most people is that they are socialized to see it that way.
The maid telling kylus about becoming lettie's( i forgot how to spell her name again) husband is kinda icky to me. I really hope the parents say something about it.
