Song Li is an ordinary girl working hard in Beijing. When she first entered society, she was severely beaten in life and work. She had low self-esteem, struggled, and couldn't help but laugh at herself. Friendship, love, and family ties are facing huge tests almost at the same time - her best friend Lin Wenyu has a bumpy love life, her ideal boyfriend Xu Jiayi breaks up unexpectedly, her workplace boss Zhou Wenrui's harshness makes her almost collapse, and the concern of her mother in her hometown makes her feel even more stressed. In the midst of laughter and tears, endeavor and confusion, Song Li and her friends used wit and humor to resolve crisis after crisis, and bravely faced the ups and downs of life. In her thirties, Song Li and her friends co-founded their own business, learned to wave goodbye to difficulties, but also calmly accepted the bitterness and sweetness of life. In the end, she grew up to be an independent, brave and optimistic "beautiful" person, and realized the transformation from "girl" to "queen".
