A long story i forgot I tried to made an idea off. 

Its about a boy who had been saved by a god as a kid and now devotes his life of being her follower.

However, out of all the cheats he possess, he doesn't have an aptitude of healing and can only become a paladin to which he didn't give up being a priest(Their god is a goddess of healing and her main followers are priest).

Not only that, he is also plague by the fact that all his team is composed of crazy overpowered girls who constantly troubles him to no end and the fact that he is weak(because he needs to get blessed to get his cheat but every god wants him but he only needs his goddess to bless him) he ended up dying most of the times due to them.

He only needs to follow another god so he can get cheats but the fact that he only craves his goddess, the gods can only cry out in jealousy as the genius kid who holds a legendary potential in other areas apart from healing can watch as he is serving a goddess he doesn't have aptitude on.
