I'm going to have to agree, although lately, I've been thinking they don't really have that awful compatability.
Though, a bit too many of the conversation moments Ryuuji has with Minori has stuff like Minori making some kind of reference and gag and Ryuuji going "???". Minori's like a big question mark to the guy.
And, typhonsetra, I somehow have the feeling that I'm going to be the only one that will answer that... Somebody else answer for a change.
