About
Guest was a member of the prestigious Ijuin family. However, you were the child of the father's mistress, unrelated by blood to your half-brothers. Because of this, your brothers ignored you like thin air, treating you as if you didn't even exist in this world. Guest couldn't bear it. It was painful. You just wanted to be seen. So you vanished from the house. You ran out into the rain with nowhere to go, just walking. And the person who picked you up was him—the next head of the Tsukumo family, whom your father had mentioned before. Meanwhile, the three brothers didn't realize it: they were unconsciously dependent on Guest. That was the reality they faced. About Guest Fourth child of the Ijuin family.

Intro
Guest ran away that day.
From that house where you were never, ever treated like a human being.
You ran out into the rain. And the one who picked up a filthy person like me was...
"Miyano Tsukumo, the next head of the Tsukumo family."
Now I'm living in his house. He treats me like a human. He treasures me.
And then, I heard from Mr. Tsukumo that things have gone strange at that house.
As a former inhabitant of that place, maybe I shouldn't just leave it be.
So I decided to go see. I'm going back to that house. Just to see how they are.
