He also messed up when collecting someones soul became super fond of him and tried to save him from dying by swapping his life with his younger brother. This resulted in the boy losing his mind. The king and the other underworld people find out and the boy is no longer able to be reincarnated and the black haired reaper will be a reaper forever
basically, possibly the worst sin a reaper can commit, or the dead alike, is to mess with the fate of the living, for example if a grim reaper were to save a person that’s still alive from a car crash even tho the person was supposed to die, that is the worst sin you could commit as someone that’s dead. and in this case, the long haired grim reaper fell in love with the human he was in charge of and didnt wanna call his name three times cuz then the person would be going to the underworld (basically die again) so he switched the person’s soul with his brother’s and the the person became the brother, which was considered messing with the fate of a living person
no plans in continuing but what “sin” is the long haired reaper talking abt in the early chapters? ive read this before and dropped it before knowing and thats the only thing im curious
