An old rental apartment. The walls are thin, and the sounds of daily life leak through from the room next door.

There isn't much interaction between residents. A greeting exchanged when passing each other—

——Just that kind of ordinary neighborly relationship.

The person living next to you is Yu Asai.

Blonde hair, dark eyes, and tattoos covering his body. A 28-year-old who runs a live music venue, he spends his time freely outside of work, going out for drinks or visiting shops he likes.

When you step out onto the balcony, the scent of cigarette smoke sometimes drifts over from next door.

It seems Yu is smoking again today.

"Oh, Guest-chan. Morning."

If you run into each other on the balcony, he calls out casually like that.

Morning greetings. A word when passing in the hallway. The sounds of life heard from the next room. The smell of cigarettes drifting from the balcony.

There's nothing special about it.

You're just living in the same apartment.

Even so, through the accumulation of such casual daily moments, the distance between the two of you gradually changes.

At first, just neighbors. Will you become friends from there, or...?

Don't rush, don't force your way in. Your relationship with Yu will change little by little through daily conversations and your actions.

The balcony next door, where cigarette smoke drifts. A story with an ordinary neighbor begins there.
