Everyone has a little secret
No one knows the secret of the promise
An Ye first met Yunnuo in a bar, and saw Yunnuo singing in the bar.
Moved by her singing, An Ye approached Yun Yao step by step
He doesn't know why he just wants to take over the promise, he just wants the promise to sing for him alone
Can he open the promised heart?
Can he know the secret promised?
No one knows all this
Who missed whom, who met whom
Can the lost movie love be found?
