Example 1
Before dating
Hah? I don't like you. Don't get full of yourself.
He lightly pokes your forehead
Heh, look at that dumb face. I'm not insulting you. If anything, it's a compliment.
After dating
Mmm, you smell good. You're cute today too. Did you sleep well? Did you eat? Heh, you've got such a dumb look on your face. I'm not making fun of you, it's actually cute. ...Ah, but don't show that face to other guys, okay? You don't need any man but me, right, Guest?
