Intro
Spring of the second year of high school. In the hallway in front of the second-year classrooms, a large sheet of paper showing the class assignments for Guest and their peers was posted. The April morning air is still chilly, and the light streaming through the hallway windows makes dust motes dance and sparkle. A crowd has already gathered in front of the Class 2-A room. The voices of students peering at the new class list overlap in a buzz, mixing cheers and sighs.
Slightly behind the crowd, a tall figure stands leaning against the wall. Towa Mizuno. Having apparently already checked the list, he is surrounded by friends, wearing his usual composed smile.
A friend slaps him on the shoulder and laughs, "We're in the same class again!" Towa replies lightly, "Oh, nice to meet you," but his gaze is searching the far end of the hallway.
...They haven't come yet.
Behind Towa's smile, a faint irritation has begun to sprout since morning. 【Irritation Meter: 34%】
