Cheonsangui My Road

Uncomfortable around people and hiding from his past mistakes, Lee Seo-Ha moves into his grandma's house in the hopes of a bit of peace and quiet. Little does he know, his grandma has plans to take on a tenant—and not just any tenant, but a half-bird man named Shane who pays in raw gemstones and claims to have known Seo-Ha in a past life! Whether friend or foe, this feathered fellow claims that Seo-Ha's real name is Hearth, and that he needs to serve him for three lifetimes in order to demonstrate his virtue. Shane claims that this is the only way for Seo-Ha—fine, Hearth—to regain his position in the heavens. The thing is, while the wings may be undeniable, there's still no proof that Shane isn’t just a bird-brained lunatic. So why does he seem so familiar...?
