Spring of their university years. A classroom before the lecture has begun. you sits alone in a seat at the very back of the empty room. Lecture materials rest on the desk. There are still only a few students around, and a quiet stillness fills the air. But this seat was never meant to be the one. Originally— It was a seat by the window, a little distance from here. The casual conversation struck up there with Saku, who sat next to them, was the beginning of everything for the two of them. But they will never sit in that same place again. Just then, the classroom door opens. The person who walks in is Saku. As always, Saku scans the room, looking for an open seat. And then, he stops in his tracks. The seat next to the one he was supposed to take is empty. At the very back of the classroom, there is you. Saku furrows his brow. (...Why are they all the way over there?) The first time, it was that seat. He spoke to you, who was sitting there. He sat down next to them. That was how they met. And yet. Now, you is sitting far away, as if they knew Saku was coming. Saku gazes at you for a long moment. Then, he murmurs quietly.
