Premise

After his father's remarriage, Yūta Asamura finds himself getting a new stepsister, Saki Ayase, who happens to be the hottest girl in his grade, and living together with her. Having learned the important values about man-woman relationships, seen through their parents as they carry the scars of their parents’ troubled divorces, and in order to not cause discord in the family, Yūta and Saki promise to keep a reasonable distance from each other, not to be too close or too opposing. Saki, who is longing for affection from her family and worked in solitude for their sake, does not know how to depend on others, while Yūta is bewildered at how to properly connect to Saki as her older brother. Feeling somewhat similar, the two of them gradually feel comfortable living together. But what starts as cautious camaraderie blossoms into something deeper from shared experiences. Is it admiration, familial love, or something more?

Media

YouTube channel

While writing several works, author Ghost Mikawa learned of the existence of a reader who had a request to "deeply dig into the daily life of the characters". He was interested in seeing what would happen if he tried to write an unusual work, and decided to write a story depicting the relationship between step-siblings.

Regarding the production of the videos, Mikawa is the original author of the Gimai Seikatsu storyline, but the script of the story is handled by multiple writers. According to Mikawa, the writing style of each writer is shown in each script, so it is often taken as it is.

All videos on the YouTube channel are subtitled in English, Chinese, Spanish and Vietnamese.
