Kouta Narumi, a second-year high school student. His mother remarried, and along with a new father, an accomplished stepsister also came into his life. Unable to adjust to this new life, he took on part-time jobs to escape his new family. This led to a routine of killing time at a late-night family restaurant until the last possible moment before returning home.

One such day, Kouta noticed another student who, just like him, would kill time at the same designated seat, at the same designated hour. Her name was Kohaku Kazemiya. A well-known figure at Hoshimoto Academy's high school division, which Kouta also attended. Possessing a beauty no less stunning than her popular idol sister, she was, unlike her sister, a cool beauty who kept everyone at arm's length.

Though aware of each other's presence, they had spent their time without making any contact. However, one day when the restaurant was crowded, Kouta was coincidentally led to the seat next to Kohaku. Then, a call came from his family. After he ended the call, Kohaku spoke to him...

"...Narumi, you also find it hard to be at home, don't you?"

Thus began their "relationship of simply killing time together at a late-night family restaurant." At first, it was supposed to be just that.

"Hey. We actually..." "—get along quite well, in many ways."

As they spent more time together, the two gradually began to be drawn to each other.
