I like everything about this story. I like how the psychopath is not psychopating. The silly FL is kinda cute, like how she's slightly dumb & clever at the same time. I never thought I'd say this too but i also like forbidden love/romance or the immoral edge it gives since they are step siblings. It is wrong, the pseudo incest & the immorality of it all but i enjoyed it. Idk why! (Thank God. I would've questioned myself if they were real sibs but whatever this story is just fiction, irl i could never!).
Also how the brother ends up falling for her and becomes obsessed (I'm usually not into yandere type) justification is not in the brothers book because he is a psychopath at the end of the day so just because he love his sister. It isn't the end of the world or a big deal. If ykwim.?? I mean he had bigger issues like him wanting to MURDER/KILL people.
The transmigration is a bonus since i like isekai, regression & reincarnation. ヾ(❀╹◡╹)ノ~
Well, slightly psychopathic but not really can be covered by [Raise wa Tanin ga ii]. One of my absolute favourites.
[ One Husband is Enough] is part horror, part psychological thriller and full Otomei Isekai. You may enjoy it.
Sadly I don't know many forbidden romances
(◞‸◟;) One of the lists may have it though! Closest I know is Rezef and Cayenna, but they haven't actually said shit. But the chemistry between siblings there is better than between the FL and ML???
I never thought I'd say this but i want more. Someone recommend me more of stories like this?? (▰˘◡˘▰)
