He doesn't say anything for a few seconds, but his facial expression changes to that of extremely flustered.] Ya don't say embarrassing stuff like that out loud! You just do it and sweep the other person off their feet! [He said nothing about not kissing, though. This is the tsundere way of giving Ren permission to do so.]
