Ai was adopted and raised by the prestigious Sanjo family. She lived there in comfort. But one day, the family's company goes bankrupt, and the Sanjos are left with an enormous debt. To help pay it off, Ai agrees to be sold at a human trafficking auction in her "sister" Shiori's place. Her heart is prepared, wanting nothing but to repay the Sanjo family for their kindness. But when Sheikh Masoud, the leader of a desert country, makes the winning bid and brings her home, the apparent stranger tells her that he has been looking forward to the day when she would become his. Without a moment to rest, he pins her down to the bed like a wild beast cornering its prey.
