Once I traveled back in time, I thought I was going back in time and could use my knowledge and experience from the future to achieve great things, but I didn't expect that I ended up traveling into someone else's story and became a villain who wasn't even a villain. Is Dieyi's tragedy a natural disaster or a man-made disaster? Is Xiaosi's betrayal inevitable or accidental? Can the little people just drift with the tide of history? Can they change the destined Bad End of "Farewell My Concubine" after traveling through time as a mistress?
