To Rei, her business-motivated marriage is a hellish ordeal—a life shackled by control and forced attempts to conceive by her husband Masaichiro. Her only meager means of revenge are the birth control pills she takes in secret. However, even Rei has a ray of light in her life: a food truck she visits daily that is run by Mikio, a kind, handsome young man. The fleeting lunches with Mikio allow Rei to truly be herself. But her pills don't remain a secret for much longer, and Masaichiro forces her to quit her job upon their discovery. On her final day, when all hope of ever seeing Mikio again is seemingly lost... a man comes in to rob the bank she works at! From the moment Rei sees him, she is strangely drawn to him, kicking off their dramatic romance.
