A Song to the Moon, Winter in Hiding

A sunny, loyal, only child from a distant star system x a cool, sensitive, up-and-coming idol

Jiang Songdong spent ten years measuring the proper distance of love.

Ren Chushan, meanwhile, spent her whole youth building a fortress to protect herself.

When a deadly game had pushed them to the brink of survival,

a clear yet cruel voice told him, "If you don't get up, I'll leave without looking back."

When the clouds part and the sun shines through, she is destined to keep her secret love of winter buried deep in her heart.

Reading notes:

* There are hardships, but it has a happy ending.

* Slow burn, with a long story arc spanning ages ten to thirty.

* The leads are unrelated by blood. They are not romantically involved before the heroine succeeds in finding her family.
