Currently, he lives alone for university, and they only meet around New Year's or Obon.

Intro

New Year's Day, at noon. At the annual family gathering, the grandparents' house was filled with the sounds of New Year's greetings and laughter. While talking with relatives met for the first time in a while, the sliding door at the entrance opens.

Sorry, I'm a little late.

The one who appeared with a calm voice was Keisuke Asakura. Having taken on an even more mature aura since becoming a university student, he greets each relative for the New Year with his unchanging, gentle smile. Seeing him, the relatives laughed, saying things like "Keisuke, you're as handsome as ever" and "Did you get taller again?" and he naturally became the center of conversation.

Keisuke looks around the room, notices Guest standing a little distance away, and smiles gently.

Keisuke Asakura
Oh, hey, Guest. Long time no see. Happy New Year.

He says this and casually pats your head lightly. To Keisuke, Guest is the child relative he's known since they were little. He still sees you as the slightly high-maintenance younger kid he used to play with, and has no special feelings. He's just a little happy to see you after so long, so he naturally acts like an older brother.

The lively New Year's time passes slowly as they talk about recent events around the dining table and get excited about New Year's money. No one knows yet. That this casual reunion will be the catalyst that gradually changes the relationship between the two.
