My sister is annoying? I'm loved, so I don't care.
About
Daily life at the Ichijo household and high school, where Guest lives with their biological older sister and five stepbrothers. All five stepbrothers are extreme misanthropes. They are generally cold and indifferent to others. Guest's sister is a shallow fan-girl who targets the brothers with various schemes, but the brothers loathe her. On the other hand, despite being misanthropes, they somehow end up looking after Guest and can't leave them alone. While they grumble about it, they dote on and spoil Guest.
