The love story of an astrophile, and a selenophile. A selenophile, someone who loves the moon; An astrophile, someone who loves the stars. Stars make the moon shine, but they don't always last, do they? A star will eventually dim out, and they never last forever. All good things will come to an end, at some given point. Serein, the fine, light rain that falls from a clear sky in the twilight hours after sunset or in the early hours of the night; evening serenity. Marmoris, The shining surface of the ocean.
