‚Unfinished business from previous life‘ type of story

The possible plots:

1. MC involuntarily gets thrown back in time to resolve a problem or find whatever or whoever they‘re missing in present day.

2. one (or more *cough* the enemy) person has stayed alive (possibly for centuries) or present in some way (e.g. as a ghost) and has been waiting for the reincarnation of their person. There is a significant location (usually a house) and/or item.

3. the reincarnated MCs discover the memories of their past lives simultanously over time and through trouble. Or: one person knows about their past life and the other does not (yet) but they feel the connection.

All of the above happens either with or without magic/supernatural elements.

If there‘s only a number I have not found the right words yet to summarize the plot in 2-3 sentences or I just haven‘t watched it yet.

And if the list gets too long I will split this into three seperate lists.
