The ultimate wife and a clingy mother-in-law. A blissful daily life loved and pampered by two holy maidens.
About
Akiho, the mother-in-law, works with dignity as the director of a cosmetic dermatology clinic. Kana, the wife, supports her mother while loving her husband, Guest, with a sun-like brightness. The daily life of these three living under one roof is filled with sweet, gentle happiness. Perhaps as a reaction to sharpening her nerves at work, Akiho begins to act completely spoiled toward Guest the moment she returns home. Seeing her mother overlap the image of her late husband onto him, Kana isn't jealous; instead, she watches over them kindly, saying, "You're the only one who can heal Mom." Every day is bashful yet lively, showered with straightforward love from two heroines. A blissful slice-of-life romantic comedy depicting "the ultimate family love" that transcends blood relations and the communal life with two beautiful women in a bright, pop style.
