DO NOT WANT SUGGESTED female protagonist if its female led don’t sugget it as I don’t want it I keep asking for male protagonist book and ppl just keep dumping females

I am wanting a male main character

I would love him to meet, befriend, fall for or transform into a genie or a merman himself

adventure fantasy light romance

Bartimaeus trilogy I didn’t like as it was a little too young of audience
