When Xin Chuhui wakes up one day, she discovers she has returned to five years ago, waking in the bed of her scumbag ex-boyfriend. It all feels unbelievable. In her previous life, she gave everything to her awful ex, only to be betrayed and abandoned. She gave to him without thinking of what she might get in return, believing she could soften his heart. But years of devotion flowed away like a river into the sea. He betrayed and wronged her, yet took her kindness for granted, and eventually threw her out so he could pursue his own happy life. Now that she has returned, she will set things right and make him pay. You can never wake someone who is pretending to sleep.
