[Mr Hat and Clogs]

Yeah, its almost like she is jealous but doesn't notice it, she's denying it or something (see spoiler).

Spoiler for One of the novels cant remember which, the treasure hunt hoax thingy..:

The Valentines day thing was kinda sweet, but just goes to show that her years of being 'miss seclusion' has borked her social skills, I thought she was being kinda sneaky at least for her, she doesn't seem to want to act out and be noticed, so she roped Yuki and Mikuru in on her plan, and included Itsuki as a recipient rather then just Kyon. (Though, I don't really know how Valantines' Day works in Japan apparently what happens in the book is kinda similar to what really happens?).

Then again she could just want to be the center of attention :roll:.
