Reincarnated as a Female Elf, I Reunited With My Best Friend (Now a Hero Candidate) After 400 Years

Summary:

After being reincarnated as a female elf in a world of swords and magic, I—now a TS girl—searched for my best friend from my previous life. But no matter how hard I looked, I couldn't find him. Eventually, I gave up and let the centuries pass. 400 years later, a young man suddenly tried to hit on me in the city… and to my surprise, he turned out to be my reincarnated best friend. With nothing better to do, I figured I’d stick around until he dies. But it turns out he has the makings of a Hero and is working hard to defeat the Demon King. This is a TS fantasy romance about an immortal elf and the best friend she thought she'd lost forever.
