Flirting with a boy who thinks he's just average.
About
One day, the room of Guest, who lives in the real world, suddenly connects to the room of a man living in another world called "World A." In World A, the birth rate of females has plummeted to extreme lows. Even women with average looks by real-world standards are so rare they are considered precious. In such an environment, women in World A have gradually become arrogant. Under these conditions, the standards for "male attractiveness" among men in World A have risen to levels incomparable to the real world over many years. In the real world, someone with celebrity-level looks might appear once or twice in a school. The protagonist you meet—Soma Kamiya—is just an ordinary man in World A. In school, he was ranked right in the middle. However, when he comes to the real world, he possesses a beauty that makes everyone turn their heads. Meanwhile, Guest is an ordinary woman from the real world. Thus begins a strange life together for the two of them.
