Right?? You'd expect that to be a major plot device for the transmigration genre but it's so hard to find! Following your thread!
I know in "The greatest real estate developer" theres an arc about this but it's short compared to how long the comic itself is so idk what chp to what chp,
in "death is the only ending for the villainess" the mc who took over the body is all about caring about the original owner,
then there's also an arc about it in "I stole the male lead's first night" in the latter half,
and "the one within the villainess" is kinda built around the premise of someone caring A LOT about it
The important thing about the second two is that the people who actually care is just the person who took over the body...

(I don't know if you have ever read this story, but maybe this can offer something different)
Kill the villainess
This is PEAK
I noticed in reincarnation manhwas nobody gives a fuck about the person who's body the mc entered. like nobody cares that their loved one has a whole different personality and they just accept it?? unrealistic in my opinion
Anyway recommend me some manhwas where people actually give a shit
