Suguru feels exhausted and his thoughts have been in chaos since Riko died, and like this no one noticed it. When they talk to him and ask if he is okay, he answers.

－“I am fine..”

Even though he is not like that at all. He needs to talk to someone. He wants to know why he is thinking. Is life without humans better?.

He sighs as he sits on a chair with his head down and stares at the floor when he notices someone approaching him and sitting next to him.
