Hidetsugu Yamabuki, the heir to the Yamabuki Group, one of Japan’s largest corporations, ends up going on an arranged marriage at the behest of his father. The arranged partner seems to be a family that runs a large company that the Yamabuki Group is merging with. In other words, it was a political marriage. Hidetsugu reluctantly heads to the arranged meeting. Appearing in front of him was his classmate Renge Tsukimisato, who is also called the most beautiful girl in school. Hidetsugu tries to refuse the engagement, but Renge seems to relieve her complex–her distrust of humans. Hidetsugu decides to become engaged to Renge even though he is skeptical. What awaits Hidetsugu is a life together with Renge, who devotes herself wholeheartedly to him. “Please leave the housework to me.” “I want to support Hidetsugu-kun, who will become my husband.” “I’m not pushing myself too hard. In fact, I’m doing great. I’m sure it’s the power of love.” What? This is a marriage of convenience, right? “Why is this girl doing so much?” This is the story of how two people who marry for convenience become a real couple.
