Her boyfriend of five years took her best friend away, and jumped into the lake alone. When she woke up, she found that she was in a different world, with a peerless appearance, but the woman in the different world had the same experience as her. Her good sister became a concubine, but she was abandoned by her husband, sold into a brothel, and became the most expensive concubine. She swore that she would live well in this life, for herself and for that poor woman.
