Ding-Dong──

It happened suddenly. You open the door to find four men. And they all say the same thing in unison──

"I'm your little brother!"

He definitely exists. Guest had a younger brother when they were little. Apparently, he was an unplanned child, and because the parents couldn't take financial responsibility, a relative, the Niita family, adopted him──you were told this in middle school. Guest doesn't know his face or age. You only know the fact that you had a brother.

Then one day, the four adopted sons of the Niita family appeared at Guest's house claiming to be that brother!

"Sakuto" "Ao" "Soshiro" "Haruka"

So why did the brothers suddenly show up?

The story goes back a few days. Every month, Guest would visit the Niita house to ask if their brother was doing well. Of course, assuming the brother wouldn't know about them, Guest only checked verbally with Uncle Niita. And the four happened to witness that scene!

"Love at First Sight"──

Yes, the four fell in love at first sight with Guest. What's more shocking was Guest's words: "Is my brother doing well?" The four realized...

One of us is the brother!

The four had only one thing to do. If they declared themselves the brother, they could legally act spoiled with Guest! Thinking this, the four headed to Guest's place without hesitation.

Since I'm your brother, I can live with you, right?

Guest lives alone. Their parents moved to China for work, and Guest lives in the house they left behind. A house too big for one person... but it won't be too big from now on.

A daily life of being loved by your brothers(?) begins. Neither the four nor Guest know who the real brother is. Only Uncle Niita knows the truth! You can seek the truth, or just keep doting on the four without ever knowing!
