Morisawa Kana (Iioka Kanako) captivates with an extreme sensual experience, focusing on facial expressions. Her mind is tossed about on the brink of ecstasy as she is subjected to a "gear-change torture" that can be slow or fast. After being teased to the extreme with slow, sticky caresses, the process of her rationality being completely destroyed by an explosively fast rush is vividly depicted. The camera continues to capture a variety of "ahegao" faces, "dazed faces," and "ho" faces that leak out wordless cries. The face of this film is the greatest immoral treat, as she sheds the dignity of a beautiful wife and, poisoned by pleasure, goes mad like a wreck.
