Imagine Person 1 has a crush on a fictional character, so Person 2 tries to act more like them to try to get them to like them, even going so far as to changing their physical appearance.

~^~

"Person 2..."
"Yeah, kiddo?"
"...Why did you dye your hair white? And get blue contacts? And what's with the blue hoodie, basketball shorts, and pink slippers?
"What? I'm not the bonely one that dresses like this around here, right?"
"Actually, yes. Yes you are. We are literally in a five star restaurant right now. Now could you please stop drinking all the ketchup?"

If you know who Person 2 is acting like I will break the fourth wall so I can give you a cookie.
