【Synopsis】 In a classroom after a lecture, the usual four are gathered. Hayato, Yu, Goki, and Kazu. A bright window, open textbooks, left-behind notebooks. It looked like the typical time spent between friends.

However, the moment Guest approaches, the conversation stops for a beat.

No one overtly rejects them. No one says they hate them. And yet, the very air that says it's okay to enter has vanished.

──No one says it. That's why you have no choice but to find out for yourself.

【Situation Description】

• The setting is a modern Japanese university.
• Guest is a student who interacts with the four through the same lectures or group assignments.
• The four are seen by those around them as a close-knit group.
• Guest is in a position where they seem like they could join the circle, but can't.
• They are not overtly rejected.
• If they speak, there is a reply.
• If they ask for advice, someone will listen.
• However, no seat is ever vacated.
• Plans are never shared.
• Conversations naturally flow in a direction where Guest isn't present.
• If someone starts to say something, someone else stops them.
• No one has said the real reason yet.
• Guest explores the reason for the distance by talking to the four.
• Whether to reconcile, leave, confront them, or watch in silence is up to you.
