I personally don’t like systems because the MC usually becomes OP, I am wondering if their are any novels with a MC that is the system. He gives out quest or just takes care of someone, well you get the idea..... hit me with what you got.
If BL is OK then Reborn as a System is a good quick transmigration novel where the MC is the system and he is not too OP
