Xia Liang had felt something missing inside her ever since she was a child. She had no idea what love was...
But luckily, years later, she met the boy who would change everything.
She had gone to such lengths to finally stay by his side and find her way into his heart, only for him to leave her so effortlessly in the end.
When they meet again, can what was broken be made whole once more?
It turned out she wasn't the only one who had never moved on.
That boy, too, had regrets.
Her boy taught her how to love someone. Beneath the moon, he promised her:
His love for her would last forever...
