Ojou-sama to Inu: Keiyakukon no Hajimekata

Tsugumi Kanada, a painter, and You Kuze, her nude model, are newlyweds who tied the knot just six months ago. While they appear to be a happily married couple on the surface, You 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 You 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. Source: MU
