I have no parents and grew up in an orphanage. I met four brothers by chance. My brothers called me Fifth Sister. The eldest brother is a rich second generation, the second brother is an agent, the third brother is the executive chef of a world-renowned international hotel, and the fourth is a fashion designer and literary young man. From the first day I met them, my life gradually became extraordinary. This is a story about Cinderella and a mermaid princess.
