Ma Kui agreed to Wang Xin and Ma Yan dating in the 36th episode of " South to North."
There were two main reasons why Ma Kui opposed Wang Xin and Ma Yan's relationship. First of all, Ma Kui held a grudge against Wang Xin because Wang Yongge did not stand up to testify when Ma Kui was in trouble, causing Ma Kui to be sentenced to ten years of unjust imprisonment. This caused Ma Kui to develop distrust and hostility towards Wang Xin. Secondly, Ma Kui was worried that the relationship between Wang Xin and Ma Yan would negatively affect their future. He believed that Wang Xin and Ma Yan's relationship was based on their appearance and dressing, and Wang Xin might not be able to resist other temptations, which led to Ma Yan's injury. Therefore, Ma Kui opposed their relationship and hoped to judge Wang Xin's true character by observing his behavior.

Fortunately, Jia Jinlong came forward to tell a lie and saved them. Jia Jinlong told them his identity and promised to help them understand the local situation. Even though Wang Xin wanted to ask Jia Jinlong about the situation, Ma Kui firmly refused, thinking that Jia Jinlong was not trustworthy since he had just met him. However, Ma Kui went to find Peng Mingjie, a friend he met in prison, for help. While Ma Kui was looking for Peng Mingjie, Wang Xin had already heard about the child's whereabouts from Jia Jinlong.
