When I first saw this and read bit, I thought it was just a shitty story of a self insert author, and with the rental girlfriend thing, it was pretty cringe. I kept trying to come back to it, cuz the art was good, and some characters were likeable. Finally forcing myself to read it, only to realise the main premise wasn't really the rental girlfriend part, and rather the relationship between the characters. One of the best stories with great worldbuilding, characters & development
