I am Lin Zang, the resident singer at the Youth Dance Hall in M20. I guard an old bookstore during the day and perform on stage at night.
One after another, women disappeared mysteriously in the dance hall, and everyone kept it secret. By chance, I picked up an ancient book of music scores and a silver hairpin decorated with begonia flowers and stained with dark red blood.
On a windy night, the silver hairpin suddenly became hot. I actually traveled back to the year M5, eleven years ago, and possessed the body of a nineteen-year-old orphan girl.
Unsolved cases spanning time and space are intertwined.
A begonia silver hairpin connects two periods of time. I must join forces with him from two time and space to clear the fog that has shrouded the youth dance hall for many years, find out the real culprit behind the scenes, save the girls who are about to disappear, and break free from the prison of their own fate.
