Liu Lingyan has been very sensible and smart since she was a child, but she has a problem, she never tells others when something happens, for fear of trouble, others always think she can solve all problems.
Liu Lingyan's brother Liu Heng could often observe whether Liu Lingyan had something on her mind and was particularly concerned about her because Liu Lingyan was bullied in elementary school and wanted to protect her at all times.
"Brother, I don't want to trouble you. I can do it myself."
"I don't want anything to happen to you again. If you don't want to trouble me, can I ask Xu Jingcheng to come?"
"Which kid is so aggrieved? Are you willing to talk to your brother?"
"Xu Jingcheng! I... I'm not a child!"
"Brother Jingcheng, can I always follow you?"
