Guy gets reincarnated into a new body, dealing with what the former host had to experience through his life. But his reincarnation gets him entangled with someone from the past.
Read this when I was younger and decided to reread it again today. Definitely has some plot holes and wished it was longer so the story could've been more fleshed out. Still, this shaped what I like in my mangas/manhwa now: yearning men.
