He thought Kabu was lying to him about who he was and his feelings for Onoe. Sanjou told Onoe that Kabu just keeps relationships for his own benefit, lying that he feels attachment to the other person. In reality, he never cared at all. So Onoe is asking what Kabu's true feelings towards him are, if he's not just using him or their relationship for some unknown benefit. At least, that's how I interpreted it.
