Review Detail of AnonyHuman in Dragon King's Son-In-Law

To be honest I don't like the fact that our MC is kept alive only because the girl's parents are kind hearted . I want there to be a deeper reason for them to be unable to kill our MC and retrive the stone/soul. This current setup forces our MC to be subservient and be extremely grateful that he is not killed like a fly by the dragons and this irks me .
