Those words surprised him, but he didn't give a sign.
"I should appologise for my behaviour as well." Tetsuo replied calmly, putting the cup in front of himself and slightly turning his head to Nakamura, avoiding looking straight at her however. Observing her actions with corner of his eye ammused him, but he didn't changed his look. After a few seconds of pause he added with a light smile:
"So, if you would take my appologises, I will gladly accept yours."
Before giving her a straight look he made another sip from his cup. No emotion but a light smile could be read on his face.
