First of all, it is a fact that most of the people who work on this show are straight dudes and naturally think lesbians are super hot and cute. Gay men aren't attracted to them and in spite of the fact they may genuinely have good intentions that are ultimately driven by their dick when not only writing female characters but female only relationships. With a lesbian relationship a writer in to women can easily just create their two perfect waifus and pair them up rather than initially starting with wanting to create three dimensional characters, and when you start like this you're naturally going to default to what you think is hot. people who write romance actually want erotica
