Ayuta Ipponyari (Hayate ICHIHARA) wants to enter Art College, but failed the entrance exam on his first try. One morning, as Auyta is jostled about on a packed commuter train, he encounters a beautiful woman. Though he has a girlfriend Natsuki Saito (Erika SAWAJIRI), he just can't get his mind off of the lovely woman he saw on the train, and he is compelled to open his sketchbook and begin drawing that profile that had become etched in his heart. Sometime later he goes to visit his father in the psychiatric hospital where he meets the train woman again. Her name is Haruhi Godou (Manami KONISHI), the new doctor in charge of his father. And, he discovers that not only is she eight years older than him, she's also the sister of Natsuki!
