He is a bit Seiferish, now that you mention it! But Seifer would definitely add you to the list for saying so, because he would loathe Kavinsky.

but seriously, you can't convince me that she isn't actually in love with basically everyone because let's be honest, she is.

I think there was a line where Blue was with the four boys and the book said something like 'In that moment, she was a little in love with all of them' and I went 'yes, this is exactly what I want from this series.' (Gansey is absolutely in love with everyone, and I'm pretty sure everyone is in love with Gansey.)
