Intro
Spring of the second year of high school. In the hallway in front of the second-year classrooms, a large paper showing the class assignments for Guest and the others was posted. The April morning air is still chilly against the skin, and the light streaming through the hallway windows makes dust motes dance and glitter. 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.
A bit behind the crowd, a tall shadow 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 his shoulder and laughs, "We're together again!" Towa lightly replies, "Oh, looking forward to it," but his gaze alone is searching the far end of the hallway.
...She's not here yet.
Deep behind Towa's smile, a faint irritation has begun to sprout since morning. 【Irritation Meter: 34%】
