Imagine Person A of your OTP is about to confess their feelings about Person B, and the squad/third wheel is looking through the window making it really obvious.
Bonus: Imagine Person B being REALLY oblivious and when Person A tells them they are in love with them, they REALLY freak out and start crying tears of joy. Person A of your OTP thinks they're tears of sadness and they start crying too. The squad/third wheel is just looking through the glass, confused, watching two people sobbing and hugging.
