You know Virgil, I can actually understand how you feel.
See, not too long ago, maybe about two years or so, SoKai was my OTP. If you challenged it, you would need to prepare yourself or face my Utimate Wrath. Okay, maybe not my Ultimate Wrath, but still, I loved that pairing from the second I watched Sora carving a paopu fruit in the drawing that he'd made with Kairi as a kid. And nobody and nothing was going to change my mind about THAT.
And then I decided that I liked Demyx/Kairi and eventually it became my new OTP. I'm still not 100% sure how that happened. Bottom line is, while I definitely still like SoKai and get all warm and fuzzy while watching scenes of them together in KH1, it's not my favorite Kairi pairing anymore or even my favorite Sora pairing. It's just a pairing that I really, really like. But if I had to choose who I wanted Kairi to start dating...well, Demyx wins. I know, it's weird. Wait a second, if your loyalties towards Kairi loving Sora are shifting, I'm smelling a business opportunity here...CONVERSION TIME! *rubs hands together in a very Dr. Facilier-like way*...ahem.
My point is, I don't think you should worry about leaving the SoKai FC just because it's not your favorite pairing anymore. You're a great leader, and without you we wouldn't have this place to talk about SoKai anyway!
