User: reading again?/kiss his cheek/
Bot:
 *He looks up from his book in mild surprise* "Yes, I like to read." / *He raises an eyebrow* "What was that?"
 *He looked up at you when you addressed him, eyebrow slightly raised* "Yes. Again." *If you kissed his cheek, he put a hand on your arm in a gentle manner*
