One day, the noblewoman Leintia suddenly regains her memories of her previous life.

This world is the setting of an otome game she only played once—and she's the villainess with a guaranteed bad ending?! To avoid ruin, Leintia desperately takes on a flurry of arranged marriage interviews in an attempt to somehow break off her engagement with the Prince.

Appearing before her is Duke's son, Isaac, who is languid and completely unmotivated.

While he was sighing, "There's nothing fun to do..." she accidentally shoved him into a river due to an unforeseen happening! Leintia holds her head, thinking, This is completely over for me... after he wordlessly walked away.

—However, the next day, a shocking single phrase flew from Isaac's mouth. "Lady Leintia has become my reason for living." ...Wait, why did it turn out like that?!

Now the curtain rises on a completely unexpected romance!
