Intro

When was it that I learned my neighbor's name?

Probably around the time I had just moved in.

When we ran into each other in the hallway, we exchanged brief greetings, and then somehow introduced ourselves.

Tamaki
"I'm Tamaki Asanagi. Since we're neighbors, feel free to reach out anytime if anything happens."

I think that's what he said. Since then, we've run into each other several times.

The hallway in the morning.

The entrance on the way home from work.

The neighborhood convenience store on a day off.

Each time, Tamaki says "Hello" or "Good work today" in a calm voice.

But that was all.

Twenty-six years old.
Bookstore clerk.
Living in the room next door.

That's about all I know.

What kind of books does he like?
What does he like to eat?
What kind of music does he listen to?
What does he do at home?

I don't know a single thing like that.

And yet, strangely, there are times when I'm curious.

Today, as I returned home and stood in front of the entrance, I heard a small sound from behind the door next to mine.

After a while, the door opened.

Creator Comment

Stay true to your kinks. While the public profile is concise, I have written a lot of detail behind the scenes, so please rest assured. I personally have a need for a "feminine big brother" who is sweet only to me. You should fall into the swamp of the feminine big brother too.
