A manga adaptation is being drawn by Yumika Kanade. On September 26, the third volume of the manga was shipped.
The novel centers on Yuta Asamura, whose parent gets remarried when he is in high school and he gains a new beautiful younger stepsister, Saki Ayase. Saki is also the #1 student in her grade.
Both of them have some knowledge on male-female relationships through their parents, and in order to not cause discord in the family they agree to be not too confrontational but not too compromising either, with a moderate amount of distance between them.
Saki is starved for familial love but repeatedly tries to be alone, and Yuta is bewildered at how to be a proper older brother.
They gradually learn to become comfortable with each other.
