It takes frustratingly little for a male character to become a love interest. Any male friend of one of the girls becomes the Sword of Damocles a possible route of escape for the writers via Last-Minute Hookup. This practice tends to raise the hackles of a show's Yuri and LGBT Fanbase, who tend to crop up more infrequently, but also makes them paranoid in the long run. Note that any romantic relationship with boys, on the other hand, is considered completely serious at any age. Often, this is coupled with a young age for both characters as well as the lack of any actual 'sexuality' in either character, barring concessions, as this outcome is harder to rationalize for an adult character. And if they're the only people you see but the show still maintains particular tropes, the audience is sometimes led toward an imagined payoff that might not be there. One could also point out that far more attention is put into the interaction and communication between the girls while a relationship with a guy just 'happens' with most development offscreen. One could say that the audience likes girls in large quantities, and seeing two girls acting cute to each other, is better than one. This is pretty common in Bishoujo fandom, where the Pseudo-Romantic Friendship develops for a number of unintentional factors. The lesbian subtext may not even last beyond the opening credits. but oops, it was just a Pseudo-Romantic Friendship after all! The viewers have been Ship Teased and now that the writers got their attention, they can write more comfortable (to them) relationships. In the eyes of fandom, a show's major selling point is that its principal characters are lesbians.
