A legend of the sea of stars, an intimate melody, an agreement between an angel and a guardian angel, and a memory belonging to two people.
An unexpected car accident and two pendants destined the fate of four people to be intertwined.
It's not her fault to forget him, and it's not her choice to forget the promise.
Meeting him was not an accident for her, nor was it inevitable that she would agree again, but they ended up in the same way. Could it be that they were just passers-by in her life.
She still remembered the agreement, but she didn't remember him. It was him who was full of expectations.
Who is the person she really wants to wait for? When will the promise that was left in a corner of her memory wake her up?
The rotating wheel of fate is playing tricks on them, making them meet each other and miss each other. In the end, it is you and me or him (her) who are holding the red thread of fate.
