Myojinjeon

Myojin was once a cursed child who managed to work his way up to being a God of the Celestial Realm. For the sin of killing his fellow celestial beings, he was cast down to Earth to live -- and, eventually, die -- among humans.

But the wheels of fate turn in the oddest of ways, for one day the baby son of a celestial deity and mortal man ends up falling into Myojin's custody. Believing that showing kindness to the child will help him be accepted back into the Celestial Realm, Myojin takes him in. But can this man, whose heart has become hardened towards both suffering and joy, rear a healthy, wholesome child?
