I know the detective is doing his job. BUT he is coming off as jealous I understand he has to bring up Kirin and Kang mom's relationship but its his tone that makes me think this.
Than he should have done his job regardless of how powerful the family is if they are close. Its weird that he will risk it all for that dickhead's mother but not for someone he feels close to. I don't make sense to me.
