I hope Ririchiyo's relationship with fox-boy (can't remember his name) improves from the recent episode on. He knows exactly what she means, she knows what she wants, yet for some reason, they can't do more than follow each other and wonder why nothing is happening. I guess he's not fully aware that she actually likes him, or is simply very good at faking it if he is.
Compared to them, Watanuki is pretty much guaranteed to score with Karuta eventually. He likes her, she likes him, and they make a cute couple.
