Astronomical Twilight [Lee Jeno]

"He was my world, but she was his sun."

The moon revolves around the earth: it only knowing as its world, never straying from its orbit. But its world, revolves around the sun--of which brings light to the world.

Kang Eunbyeol, an astronomy enthusiast, who would risk almost everything just to gaze at the stars, coincidentally finds herself in a situation with an enigma who is Lee Jeno. A coincidence that marks the start of mapping his feelings, a journey to try and understand him further. Had she known that her stargazing rendezvous would turn to her admiring the moon instead. But what if he was already fixed on someone else?
