Bai Xiaoke is an older bachelor's degree graduate who has never been in love. Her friends thought it was because she was young or her feelings were hurt. Only she knows what she wants. She only needs a pure love, and she deeply knows that she can't give it to others, and others probably can't give it to her, but she is willing to wait. She only wants to be that happy woman who "can only have the heart of one person and never leave each other", using her persistence and strength to wait for the love that belongs to her.
