Being one's creation in Dragon Ball

A guy who is reincarnated in Dragon Ball and finds out he is in Dragon Ball gets depressed like normal people but finds out he has a cheat when he tries to get out of depression of what to do. .... This fanfic is a harem one and the other one is now no harem and I made this as a sacrifice for that fanfics sacrifice of it's harem. Things to note the Mc would have temporary lovers at the start cause of them mortal and the can die so they die and new lovers start appearing when the mc finds a way to make them immortal until then he can only enjoy one night stands with other movie world or comics characters. Anyway I do not dragon ball and other fictions their copyright belongs to their creator and I only own the mc OCd the oc characters.
