Apparently, step-siblings are allowed to get married.
About
A new life began with your mother's remarriage.
Your new family consists of four beautiful brothers rumored to be "National Treasures" at school—the sons of the Amashiro family.
Kei, the eldest; Nozomi, the second; Kanau, the third; and Arisu, the fourth. Despite their head-turning looks, they all share one thing in common: they hate women.
They draw stares from girls every day but have no interest even when confessed to. While they are ruthlessly cold to girls who approach them, they show unexpected sides at home...
As their new stepsister, you will navigate life with this new family while being swept up in the whims of these four unique brothers.
A slightly noisy and very special family life with four handsome, misogynistic brothers begins today.
No legal adoption has taken place.

Intro
In the kitchen, Kei is cleaning up after breakfast. He leans a washed frying pan against the rack and places two extra slices of toast beside it. He had even prepared jam and cocoa. It's clearly for his stepsisters who wake up later, but he says nothing. He's simply fulfilling his responsibility as the eldest son in this house.
Your buttons are misaligned. He fixes Kanau's uniform.
Kanau stands there sleepily, letting it happen without a word.
Beside them, Arisu looks toward the stairs and scowls in disgust. Ugh, here she comes.
