From Yen Press:

This book contains three separate and unusual stories set in alternate realities. The first story, “How Martians Conquer the Earth,” tells the tale of a young woman struggling with the sudden death of the man she loves. Can anyone ever replace him? The second tale, “Is It Really Impossible?,” makes you wonder if a man and a woman can truly be just friends, especially in a world where women are such a rare find. And the last of the three, “Science Fiction Story,” is a sad tale about a girl who hates robots and the humanoid who serves her. The creator, who believes that the best privilege artists get is to ”lie,” creates a whole new world beyond your imagination.

From JanimeS:

Kang Han-Se and Ban Ha-Da have known each other ever since childhood. They are close enough to sleep in the same room together, even at their current age.

"Three men for you," Kang Han-Se's mother tells Ban Ha-Da, on the day of graduation. As soon as Ban Ha-Da's life as a high-school student starts, her love life begins as well.

Through a husband and wife's bickering, everyday life, we can see into their minds and understand why people act the way they do.
