In the next 1 or 2 episodes, Lawyer will make their (ML and FL) relationship awful. Will see their breakup soon. And I think he is the mastermind behind all those bad things.
Later on, Coach Xiao Han probably will use the information he gathered about Coach Zhuang Yue (Shao Bei Sheng's Mother) and Shen Zheng Yi's Mother for his own interest to create misunderstanding between ML and FL.
