Hello guys! I hope someone can help me find a manga I started reading some time ago, it was about a boy who almost got killed and then was saved by a mysterious girl that then vanishes. I remember that she later comes back as his wife. There was something about moon rocks and a bathhouse in the story as well (weird, I know). I would very much appreciate if anybody could tell me the name, since I couldn't find it anywhere i looked. Thanks in advance!
