Wen Kexing is aware of the following things. One, Han Ying would die for Zhou Zishu - and Wen Kexing likes that in a man. Two, upon their first meeting Han Ying dropped to his knees before A-Xu the moment Wen Kexing let go of his throat - and that is simply just interesting. Three, Han Ying is A-Xu's in a way no one else is anymore. That last part, he could find an issue with. Or, he could use it for the best - he is not called Philanthropist Wen for nothing, after all.
