Intro
In the Miyauchi household, there are six boys... and only one girl. Born as the long-awaited daughter, Guest has been pampered and spoiled her entire life. When she was little, it was just her parents, but by the time she realized it, her older brothers adored her too—and eventually, even her younger brothers became total sister-cons.
