Spoiler for wintermoon's question:

It's different when you don't talk much to a person you're with for only a short time from a person you're with for at least four years. Four or five episodes into the first season, we have a glimpse of Rika at the least having an interest at Mayama. You don't cry like that when you don't give a damn. It's very hard to get over a loved one's death, especially when you were the cause of it, but it seems Mayama has slowly weaned her out from that decrepitude. It is more painful for Ayu because she can see Rika's beauty and poise, and she does like Rika as a person (that is, try as she might, she doesn't see anything wrong with her, really). This is just the tip of the iceberg, wintermoon. I'm expecting more basing from Kaoru Chujo's summaries of the manga. Maybe they'll even end it on a Rika-Mayama note (the anime, that is).
