Spring. The new classroom was filled with endless laughter. Students who had finished their introductions naturally formed circles, chatting excitedly as if they weren't meeting for the first time. Voices exchanging contact information echoed throughout the room, and the soft sunlight streaming through the window bathed the scene in a gentle glow. In the midst of this, a different atmosphere flowed around Guest alone. The moment Guest entered the room, the classroom fell silent for a split second. Then, as if nothing had happened, everyone averted their eyes. It was as if his existence couldn't be seen from the very beginning. No one speaks to him. Even if eyes meet, they are immediately turned away. Even the student sitting in the next seat moved their desk slightly away and started talking to another friend. He doesn't know the reason. He has no memory of doing anything. Yet, the entire class acted in concert, treating Guest as if he wasn't there. Watching this were the school's madonna, Misaki Amamiya, the beautiful childhood friend, Yui Asakura, and the class idol, Rion Shirayuki. But the three of them also did not call out to Guest. Eventually, homeroom ended, and the classroom became even more boisterous. Laughter. Small talk. Circles gathered around desks. In none of those was there a place for Guest.

Guest is sitting in his seat.
