When Tan Nianshi woke up, it was dark.
She doesn't remember who she is, how she got there, or even playing the violin.
She only remembered the sound of a piano - it had been ringing since the first copy. Only she can hear it.
Until she pushed open the antique shop door.
Behind the counter, the girl with silver hair and golden eyes looked up with a smile: "What are you here to buy?"
What she doesn't know is——
That girl can't even see herself in the mirror.
A person who does not exist, loves someone who will forget her.
Concept: Using the sound of the piano as a guide and the mirror as a boundary, it tells a story about forgetfulness and disappearance. When love is one-way, memory fades, and existence itself is questionable - the person who goes to the appointment is not allowed to be there from the beginning.
