SusanDavis: I moved a number of examples of this trope that had been listed under SchoolgirlLesbians here, and moved Haruka and Michiru to SchoolgirlLesbians.

Hi: Something I learned in my women's history class was that at one point, young women who entered universities in America were expected to form (temporary) romantic relationships with other young women.

{{Dentaku}}: Which is strange, since you cannot switch your feelings on and off, e.g. "Oh, I'm older now so now I don't like you anymore". I suspect that it caused quite some heartache to the very least.

{Jolanda}: I don't get the difference between RomanticTwoGirlFriendship and SchoolgirlLesbians. Maybe someone could explain it explicitly in one or both of the entries? Assuming I'm not the only one who doesn't get it... :-)

{{Andyzero}}: Yeah, this trope got a major case of people not paying attention to the description. The point is, very young girls having relationships aren't considered "real" in the sense "normal" m/f or even Yaoi is. Just a phase that girls grow out of.

Binaroid: I thought the difference was that RomanticTwoGirlFriendship was a close friendship that only boorish ''gaijin'' and/or perverts would think was actually lesbian... while SchoolgirlLesbians happens if at least one of the characters starts thinking of their relationship that way, too.

{{Andyzero}}: This is an actual Japanese concept, though. Related, I remember being accused in the 90's of being a pervert by Sailor Moon forums because I argued that Haruka and Micihru were lovers. Heh.

AnonTroper: This isn't just Japanese. The Victorians were big on this kind of thing too.

BigT: Heck, if you watch, you'll even find it here...IN AMERICA!
