[Kaname's words do nothing to calm him, but Conrad covers his upset by swallowing and averting his eyes. He's ashamed of his weakness and... apologetic that Kaname should have had to experience that.]
[The thought that it was an invasion of privacy on the most personal level possible enters his mind and is dismissed immediately. Whether it was Kaname's intent to pry into Conrad's feelings or not, his words convey sincere sympathy. But not, as far as Conrad can tell, pity.]
[He's grateful for that.]
I'm... sorry. [Somehow it feels right to apologize. He caused Kaname pain after all. But... Kaname knows his feelings now, and that's, selfishly, a relief. Even if Conrad will still hide them.]
