Kirara dies trying to get to her wedding and gets sent back to sabotage it. The entire plot runs on the cruelest joke possible: the stronger your love, the more perfectly you can destroy it. A ghost watches her younger self fall in love with someone she knows will leave, powerless to stop either of them.

Kirara's wedding day becomes her last when a car accident cuts her life short at twenty-four. The strength of her love earns her a second chance, but with a twist: she returns to earth as a ghost, sent eight years into the past to the moment she first meets her future husband. There she finds both him and her sixteen-year-old self, long before they became a couple. Kirara hopes to use her ghostly powers to hurry her younger self's romance along, but her meddling may push her teenage counterpart away from him entirely. The result is a supernatural romantic comedy with ecchi and slice-of-life touches.
