*facepalm* Dudes...your all wrong. She was putting a lovenote into Kitamura's schoolbag when Ryuuji walked in. Embarrassed and freaked out, she ran across the room to hide in the locker, kicking up desks and chairs in her wake. But when she slammed herself into the locker she knocked it down and she came rolling out ;P I should also note that in the novel thats note really what happened.
