When Akane unexpectedly crosses paths with the striking young noble, Louis, from another realm, they quickly forge a close friendship. Louis frequently journeys between his world and Earth to be with Akane, but a time distortion complicates their connection. A month for Akane equates to an entire year for Louis.
After spending significant time together, Louis, now a handsome young man, musters the courage to confess his feelings to Akane. However, when she turns him down, he returns to his world, heartbroken, and vanishes from her life.
In the wake of his absence, Akane begins to understand the depth of her own emptiness. Determined to find him, she utilizes the magical "Transfer Portal" that Louis left behind to venture into his world. Upon their reunion, Akane is surprised to discover that Louis has transformed into a charming marquis!
