Cecilia was enjoying her daily ritual: a blissful solo midnight snack time. Today's dish turned out perfectly! But as she was excitedly carrying it, she bumped into her husband, Alphonse, who had returned home earlier than expected... "What is that?" "...A freshly baked Quiche." "...I'm hungry." "Um... would you like some?" The relationship between these two—whose "White Marriage" (unconsummated marriage) contract has only one month remaining—begins to shift following this one night. A slightly bittersweet "time-limit" Love Story between the eldest-daughter-type poor Earl's daughter Cecilia, and the ruthless (?) Duke and Knight Commander Alphonse.
