Ryosuke finds out his wallet is missing, and then he sees the cat yawning. He thinks the cat is mocking him until Akane and Haru stop him from yelling at the poor thing. Haru has to go to work, and Akane scolds him for losing 50,000 yen. He explains that he is buying a camcorder that was on sale. As he and Akane glance at a child playing soccer, the soccer ball goes into the street with the child going after it. Suddenly, a car is about to hit him, but Ryosuke saves the child (Taisuke). The father rush to see his child who started to cry, and Ryosuke comforts him with candy. Later, Ryosuke looks at the ball that Taisuke gave him. Akane tells Ryosuke to be careful, but Ryosuke states that he had to save him. Otherwise, Taisuke would have died. Ryosuke jokes about dying, but Akane doesn't like it especially if Haru hears it. Then, Ryosuke loses the ball; it hits the elderly lady. Moments later, Ryosuke helps the elderly lady get to her home. The man (Mamoru) offers them, 1 million Yen, but Ryosuke declines the money. Though, Akane seems a bit saddened with Ryosuke's choice. On the streets, Ryosuke looks at his Joint Man doll that was his reward. He tells Akane that his roots are weak since he has no relatives. His only wish is leave something of him that shows people that he enjoys life.

With that said, Akane teases Ryosuke a bit about how he can raise money to but the camcorder. Ryosuke tells her that he might sell this doll which Akane doesn't think so. Out of nowhere, a nerdy man shout that it's the first edition doll. Both Ryosuke and Akane are shocked at this revelation. The nerdy man begs Ryosuke to give it to him, but Akane states that there should be a price for it. As the man goes through his wallet, Ryosuke realizes that it's his wallet. The nerdy man explains he bought a camcorder on impulse which is the one that Ryosuke was going to buy. Just as the man thought he was safe, Ryosuke and Akane decides to turn him in. Brief scenes of Haru, Ryosuke, and Akane are seen in film.

Bossun is seen watching the film. He narrates about Akane, his father, and Haru. He goes into the closet to look for his art supplies, but a heavy box catches his eyes. He watches the tape and remembers that his mother did not talk about his father. He watched four tapes so far in the exact order out of nine tapes. One day, his mother comes in and notices the box. She asks him how far he watched before locking it up. When Bossun asks her about his father, she tells him that he's a worthless person without even telling him. Then, Rumi comes home and makes Bossun mad by asking him to bring pudding for her on the day of his birthday. Later, Bossun walks from the store to buy almond jelly for his mother as he thinks about how his mother divorced another man after Rumi was born. He gets suspicious a bit and looks for the tapes. Then, he decides to go through the photo albums and notices that there's an unusual skip. The next album has pictures of him as a baby. Also, he notes that there's not much photos of Akane and Ryosuke. A breakthrough occurs just before he starts to quit. He notices a photo of his mom. In the living room, he brings the suspicious photo and points out the date, August 13, 1994. He explains she's not pregnant by the time he was born on November 11, 1994. He asks her if she is really her mother. Akane gives the album to Bossun, and both he and Rumi look at the photos. Akane explains the truth to Bossun that Haru and Ryosuke are his biological parents, and how she met them. Later on, Akane hopes Ryosuke has lots of children after hearing his goals. When Rumi asked about Bossun's parents whereabouts, Akane explains of how they both died in separate car accidents in the same day, the day of Bossun's birth. For Haru, Akane drives Haru to the hospital, but they got into an accident. For Ryosuke, he dies when a car struck him with a soccer ball seen flying in the air. Upon hearing his parents' tragic death, Bossun runs from home and thoughts of loneliness are in his mind as he stares at the starry sky.
