Well, in the beginning I was rooting for Kyoko x Ren. But I hate how much they hide from each other (their pasts, feelings, almost everything T_T) and how reserved they both are with each other. Since Ren is being a pansy and not doing anything about it, he's been making me angry.
Which is why I love Reino and Sho. They're both so open about their feelings for Kyoko. Especially Reino, lol.
I hope she gets together with anyone but Ren at this point. (Since it seems that's never going to happen, anyway!)
