but there is a small chance she is a lez...i mean who gets crazy about a picture of Sakaki in a bikini like Kaori did in episode 5?
I'll give you that, yeah, but Sakaki is Kaorins idol and so given the chance to see your idol in a swimming suit few people wouldn't spaz out like Kaorin. And another contributing factor for her spazzing would be that she doesn't see Sakaki that often and was given the chance to go with them but didn't so it would make her upset and thus spaz out.
I don't think Kaorin is a Lesbo, maybe she's bi, but not a lesbo. You can think what you wanna think though.
