Rino is a talented cook, and her husband Keita is kind and caring. Together, they appear to live a happy married life. But on the night of their wedding anniversary, everything falls apart when Rino receives a livestream video. In the video, a masked man, her husband, is intimately involved with an unfamiliar woman.
After discovering his betrayal, Rino storms to the scene of the affair and, in a fit of rage, repeatedly stabs Keita. However, she is counterattacked by his mistress, Elena, and loses her own life as well. When she opens her eyes again, she finds herself back on the very day she first learned of her husband's infidelity.
Determined to take revenge on both Keita and Elena, Rino tries every method she can think of. Yet each attempt ends in her death, only for time to rewind once more. Why is she being sent back? Was there something wrong with her revenge? As she becomes trapped in an endless cycle of death and repetition, Rino gradually uncovers a shocking truth.
