(Disclaimer: This is not a cool novel. The heroine is pretentious and has big flaws in her character)
Bai Luo has good looks, a high IQ, and maybe some people's love, but other than that, she has nothing. In fact, it's not that she has nothing, it's just the influence of her family environment. If it's only a small part, to her, it means nothing.
So after she was "disappointed" by everyone, she decided to work hard and become the best version of herself that she could be.
But, is the best version of herself that she thinks really the best? When she calmed down and looked back, she realized that she had thrown away the only person who could make her feel happy and free. She had thrown away her happiness with her own hands.
