Ok, so I’m looking for this yaoi manga I read years ago that I didn’t get to save, the story went as follows:
MC decides to randomly go out and have a one night stand where he meets the ML and brings him back home
The next morning he wakes and of course ML is gone but then he bursts through the wall and it turns out ML was actually a demon prince
He says a family heirloom is stuck inside the MC and he needs it back to become king, they don’t know how it got there but decide that if they have sex and recreate that night maybe he can get it back
So they start a sexual relationship which of course turns into love and the heirloom gets returned after they share a mutual love! As it turns out ML transferred the heirloom in the first place because he fell in love at first sight and wanted to give him everything
Absolutely love this story, always find myself coming back to it for the characters and art
