"Ambiguity makes people suffer, and ambiguity makes people greedy." If you like someone, that person doesn't hate you, it's just ambiguous.
Sang Yu and Zi Yu, a man and woman struggling in this ambiguous relationship. Sang Yu, who has a blank relationship experience, meets Zi Yu, who he once deeply loved. Is it lucky? Or was it a profound lesson God left on her emotional path?
And how will Ziyu end this damn ambiguity?
