Time Travel: the Princess and the Princess Are Maids

His grandmother worked overtime and got robbed when she came home in the middle of the night. The young lady struggled to resist, but was hit hard on the head by the gangster with something. She fainted. Before she fainted, she seemed to see a light. Hey, where is this? The house was not shabby, but I was wearing tattered clothes. I stretched out my hand to touch my head and saw that my hair was long. I have always had short hair. Wait a minute, wasn't I robbed? I remember getting hit on the head, how did I end up in this shitty place. I won't be able to travel through time, right? Mamma Mia, who will save me?
