Description

First Flower.Koshiro Saeki is recovering from breaking up with his girlfriend Shoko Akimoto. On his way to work on the train, he first meets Nanoka Kohinata while returning a train pass that she dropped as she was trying to exit the train. After returning to his house from work, he finds out from his father, Zenzo Saeki, that his sister, whose face he can no longer remember, will be moving into their house for an easier commute to her school. The next day, Shoko visits him during lunch break to get back the key to her apartment. At the end of the work day, a customer gives Koshiro's co-worker Kaname Chidori two tickets to the theme park nearby. She gives them to Koshiro, suggesting that he get back together with Shoko. Upon leaving the customer's office, Koshiro meets Nanoka again and impulsively gives the two tickets to her. She suggests that they go together, and they spend the rest of the day at the nearby theme park, later consoling each other on their love lives. Their father appears at the end of the day to pick Nanoka up, revealing to both that they are siblings.
