He won't let her control him, he likes men, is pretty monogamous. She probably has done something heinous in retaliation, it would not surprise me if she had a hand in what happened to Ziyu.
I have two theories why they donât get along:
1. She killed his previous partner.
2. She is not his biological mother, but was forced to raise him as if thatâs the case. Why she would agree? Donât know.
