Des：Yuki is a beautiful older woman who moves next door as a single mother. Asano cared about her very much. She had just been divorced and seemed to be having a hard time. One day, Asano, who wanted to help but couldnt muster the courage to do so, witnessed an argument between Yuki and her ex-husband. She immediately stepped between her ex-husbands sword, seemingly about to attack her, but was beaten instead. His self-centered behavior hit Yuki in the chest, and the feeling of distance between the two deepened. Their relationship has developed from mere neighbors to an irreplaceable relationship.
