It's about a boy who often falls for girls. But once he confesses to them and they agree he doesn't like them any more. And he always consults his best friend who is a girl. While wondering when he'll find someone who he will always like he begins to develop feelings for his best friend. She doesn't know what to do. Her friend suggests that she should just date him for a while because he'll get bored soon enough and they can return to being normal friends. However, while dating she sees a cute side to him and starts to develop her own feelings for him. He happens to over hear her friends talking about the original plan to date him for a while until he got bored. After hearing this he apologises to his friend saying that it's like always, he's lost interest in her. They go back to being friends but secretly still hold feelings for each other. I think they were in school near the stairs at the end when they get together....
