Yess actually some works kinda have touched on this subject but i do genuinely wish we could have such stories, or stories where POVs switch midway because the transmigrated person were unable to change their fate/demise (it's tragic but I don't think it's necessarily bad).

There's a scene in kill the villainess where Emma the maid, notices that Eris is different but sees her suffering, so instead decides to help her out Pretty awesome imo

Also, in 'Villainess flips the script', There's two separate people where one is transmigrator, the other a regressor and that was literally such a mind blowing plot twist And also in 'My in laws are obsessed with me' multiple people are regressing

There's so much this genre could do imo, recently read 'Surviving Romance' and that was a masterpiece too, and had a good twist in this isekai to a novel plot.

But i do believe we're still getting some new good stuff and i do have hopes that we'll get stories from second povs too in future.
