One could say the same about Wicked. Wicked loves Feng Lan, but felt nothing for Prince until he realized he's Feng Lan. At which point he started treating him as a girl ("don't go drinking with guys", "don't sleep out in the open", etc).
Furthermore, (more clearly in the novel) Feng Lan herself said that she feels restricted when she's a girl, and can be herself as a "guy". Going by that, Gui loves Feng Lan's real self while Wicked loves the Feng Lan who unwillingly tries to abide by society's standards of a girl.
Games are great and all that, but there's no substitute for knowing someone in the real world. As far as I'm concerned, Gui's love doesn't count for anything until he's loved her in real life.
Also, of course Wicked didn't love her at first as a guy. Can you honestly expect most men who self-identify as straight to be able to see a guy the same way they might see a girl? Gui, on the other hand also said he was straight, so when he met with her in the real world, as a girl, he should have been able to look at her as a potential love interest, without the barrier that our perceptions of who we can love creates. In other words, Wicked has an excuse. Gui doesn't.
Remember that Second Life is a virtual reality game that has 99% realism as its selling point. Yes, it's a game, but they're not sitting behind the anonymous computer screens that this era has. There may be no substitute for knowing a person's RL self, but what does that matter if the RL self is suppressed and the in-game self is "real"?
As you say, Wicked, self-identified as straight, is normal for not falling in love with Prince, but Gui, self-identified as straight, actually fell in love with Prince despite "his" gender. Also, as I said before, Feng Lan is her true self in-game but hides it in RL. That is why it's reasonable for Gui to not recognize the carefree traits that the female Feng Lan suppresses in RL, but a bit questionable for Wicked, who has known her for years and thus already knows Feng Lan's true self, to feel nothing resembling love towards the male Prince he interacted with in-game.
As for RL, there has hardly been any interaction between student Feng Lan and professor Gui. It's unreasonable to expect Gui to fall in love with Feng Lan when the most they've done is have a short chat about Prince over lunch. Furthermore, he is a teacher and she is a student - he can't just go around looking at his female students as potential love interests. And that's not even mentioning the fact that he's in love with Prince, so why even look at girls as potential love interests in the first place?
But I digress. My main point is that Wicked sees Feng Lan as a girl, and if she was male, he would not love him. Gui sees Prince as a person, and male or female, Gui would love him all the same. This is particularly important because Feng Lan's personality is more "male" than "female". If she got together with Wicked, he would only continue restricting her "true self", nagging her when she doesn't act ladylike, as opposed to Gui, who loves her as she is.
