I'd like to see a story where no immediate reincarnation takes place, but adjourned one. Where everyone in this story knows about previous owner's death and that now body possessed by another person.
Because I'm tired of this overused trope in manhwa and especially in chinese novels, where real daughter/son died from abuse and neglect, then MC takes their place, fights back and SUDDENLY everyone starts caring about deceased daughter/son body with another soul in it, and turns out MC had loving family, powerful bloodline/artifact/heirloom etc...
This concept is completely unfair to the original owner of the body.
