Like, imagine a guy and girl having a playful, teasing, flirty relationship, and then the guy sort of steps over the line and does something rather naughty, and in response she makes this expression where she sort of pretends to be much angrier and affronted than she is, and she goes after the guy to punish him, playfully, but with a little sting to it. Like, if he's far away, she would probably stride towards him and throw something at him, or if he's sitting right next to her, she would probably hit him hard in the arm, or pinch him really hard. In my mind I see this mess of pursed lips, inhaling, and smiling. And her eyes try to look serious, or something... lol, been trying to imagine this expression for too long now. Any ideas?
