A month's repetition, four hearts.
Twenty-nine midnights, a single answer.

November 1st to 30th—In the frozen cogs of a city, starlight reflected on glass, and the pulse of a machine,
your single step changes the loop.
Sieru, a dancer who remembers time, Aria, an astronomer who calculates stars,
Marianne, a craftsman who manipulates cogs, Viola, a magician who weaves illusions—
Four different rhythms of love dance toward the same time.

*** Story Summary

Sieru – “The Name of Spring”
In the repetitive day, a single, unforgettable emotion.
Her toes once again move time.

Aria – “Phases of Starlight”
At the boundary between logic and emotion, an unerring formula for love is completed.

Marianne – “The Oath of the Drawing”
A rough yet warm hand that seals hearts with mechanical precision.

Viola – “The Card That Never Disappears”
Between illusion and sincerity, the final magic blooms on reality.
