I would like to see more stories where Uke or Seme loses the memory of their loved one through supernatural means. 1b6w6f

Reincarnation stories don't count.

The stories I've read that have addressed this topic so far are The Tiger Is Descending and Two Moments in Time. I would love to see more stories about this. (These examples only had Uke forgetting about Seme, but you can also recommend some stories with the reversed case if you know any)

Here are some with forceful memory erasure but they're sooner technically/medically induced than supernaturally to be honest,
I Want to Be a Big Baddie

You may have luck with searching the tag Memory Erase (the link is a search for Yaoi only)
