People who grow up together can be childhood sweethearts, or simply from the same village.
Liu Ruyan and Ji Boda grew up together!
They were inseparable. As children, Liu Ruyan promised she would marry Ji Boda.
But as they grew up, Liu Ruyan met Yiteng Cheng, a dance student. She thought she had found her Prince Charming, while Ji Boda laughed at the promise they had made as children.
Neither of them could tell whether what they felt was familial affection, friendship, or love.
Gradually, Ji Boda drifted away from Liu Ruyan.
Only then did Liu Ruyan realize she had lost the person she loved most.
