Painter Tsugumi Kanada and Yoh Kuze—who serves as the nude model for her art—are newlyweds who tied the knot just six months ago. While they appear to be a happily married couple on the surface, Yoh is actually a fake husband whom Tsugumi bought for 30 million yen to escape an unwanted arranged marriage. As they live together under the same roof, Tsugumi and Yoh gradually begin to open up to one another. Yet, a monumental secret stands between them... A story of a bittersweet and frustrating contract binding two wounded souls—a relationship that began neither with love nor romance.
