The ending of Ode to Joy did not explicitly state that Shengmei and Lawyer Cao were together. In the ending of the novel Ode to Joy, Andy and Wei Wei got together and Qu Xiaoxiao and Zhao Ruiwen got married. Thank you for reminding me to answer this question.
The actor who played the role of Cao Guang was Wu Jing. Cao Guang, the character that appeared in the novel, was a computer science student and Weiwei's classmate.
It seems that you are very familiar with the plot of Ode to Joy. You might need me to give you a few more recommendations so that you can read it more happily. In that case, I recommend the following novels to you: "It's Hard to Pry a Lawyer's Corner","It's Not Wrong for a Lawyer to dote on His Wife", and "Soft Side". I hope you like this fairy's recommendation. Muah ~😗
