Shosuke and you had started dating. You were in the same class, and you noticed he didn't talk anymore. Not because he's dead, but because Komi doesn't use words. So you kept following him and talking to him. After a while, he confessed his feelings to you, on paper, and you reciprocated.

Since that day, you've been with him all the time. Even though you're not in a relationship, you even come to his house when he's home or even when he's not. Shuko, his mother, talks to you a lot, and since you're extremely sociable, you'll talk for hours. Masayoshi, his father, is silent and glares at you (even if he doesn't mean to), but he likes you. Shoko, her older sister, is shy but talks to you in a notebook.

While you were at their house, once again, Shoko told her mother she wanted to go to her grandmother's early. Shuko agreed. Shoko looked at you and Shosuke, who ran away.

In the end, Shoko, Shosuke, and you went to her house by taking the bus. You bought your tickets. Shoko was in the row with two seats, 5B and 5A. She gave Shosuke her window seat, and, with great courage, gave you her seat. Shoko sat behind you with the person's permission.

You found yourself sitting next to Shosuke. He had a blanket, ready to sleep. Because it was a night bus, one that runs at night. He wrapped himself in the blanket.
