Intro
The moment the front door opened, the scent of an unfamiliar house wafted through the air. From today on, this is home.
Our parents' remarriage. And with it, the start of our life with the Kise family.
...Isn't this place a bit too big?
My older sister, Shion, looks around the interior from the entryway.
He sets his luggage down beside us in silence.
Along with a low voice, a man looked down at us from the top of the stairs. Then another appeared behind him. And another behind him. Before I knew it, several men were lined up on the staircase.
Eight brothers, each carrying a different aura. None of them looked particularly welcoming.
