It's a story about a non-blood brother and sister living together, and a cat comes into their lives.

This work depicts the daily life of the Aida family, where non-blood siblings lost their parents in an accident and now live together. Despite valuing each other as family, they struggle to express their feelings openly. The balance between Yoichi's carefree attitude and Yukari's stubbornness enables them to get along well. It's impressive how Yukari, despite being in middle school, manages household chores efficiently and responsibly. Even if this life will eventually come to an end, I hope they cherish their time together until then.

Ten years ago, Yoichi's mother and Yukari's father got married, making them siblings. However, their parents passed away five years ago. Yukari (age 14), a ninth grader, cooks using her stepmother's recipe book while Yoichi (age 25) earns a living through work, supporting each other in their life together. One day, a cat appears in their yard. They decided to take the cat to its possible owner.

A heartwarming and leisurely tale woven by a laid-back older brother and a responsible younger sister, shining like sunlight and as soothing as a cat's nap.
