Going back to what moezy-chan and moonprincess were saying earlier about Naoko, there was a Valentine's Day CD that focused on how Naoko felt about being single. Does anyone remeber this? These were audio stories, each track focusing on what a different character did Valentine's Day. Because Naoko doesn't have a special someone, and I apologize if I misunderstood this, she gives all her friends chocolate. And she wishes them luck on their crushes.
So, there is a short-story that shows Naoko's point of view.
