It's actually not forbidden for idols to have relationships in Aikatsu!. In the first season, Orihime said that she wouldn't mind if the girls started dating as long as they didn't stop showering the fans with the same amount of love they did before the relationship.

Also in real life, its not forbidden for idols to date. Rather they can date but they just have to hide the relationship and make sure the oublic doesn't find out. I don't know much about Japanese idols, but I know with Korean idols they're allowed to date freely if their company announces it.
