Yu Lan had loved Sheng Youting for 11 years despite no response from him. Inferiority became part of her when she was with Sheng Youting. However, when she found it was so hard to continue her unrequited love and finally decided to exclude him from her world, her heart ached extremely and it nearly cost her life.
