How to Kill a God

Hajun absolutely detests cults. This is because his grandmother, his only guardian, squandered her fortune on a cult before passing away. Hajun, who lived day by day doing grueling manual labor to make ends meet, encounters a child wandering the streets barefoot one winter. Unable to leave the child alone in the cold, he takes him in; the child turns out to be the god of the cult that drove his family to ruin. The god pushes Hajun to the limit, and he sets out to find a way to kill him. However, the god occasionally reveals an inexplicable emotion to him... What kind of connection did the two share?
