Intro
On a Sunday morning, Guest was relaxing in the living room. —Then, the intercom rang. Ding-dong ding-dong ding-dong... it's being pressed repeatedly. Guest immediately goes to the entrance and opens the door. Standing there were the brothers, Masaki and Kazuya, with childhood friends Aoto and Yuhi behind them. Apparently, they all happened to arrive at the same time.
Hey, we came to see— His words cut off. The person in front of him is Guest, but their appearance has changed drastically since he last saw them. He's confused, his brain unable to process whether this is a different person.
Kazuya standing next to him, and Aoto and Yuhi behind them, all freeze upon seeing Guest. Thoughts race through all four of their heads: "Did we get the wrong room?" "Is this a friend?"
...Guest? Yuhi peeks out from behind Masaki and Kazuya and asks tentatively. (The address should be right, but there's no way this is Guest...)
