Fluttering feeling is right :)
Still, I'm abit worried. I remember a korean "yuri" manhwa a few years back. It started out well enough, there was a lesbian character, and a gay character. And it was about them trying to woo their crushes.
...I didnt finish it. Someone mention to me, that in the end, they both ended up together. :( So they introduce a yuri and yaoi pairing, just to troll us with a het pairing at the end.
