Imagine your OTP standing on a skywalk, pre-relationship. They nervously watch the cars underneath them go by, and person A sighs nervously. Cautiously, they turn to person B and confesses quickly, wincing in anticipation of rejection. But they hear nothing; B doesn’t say anything, doesn’t move. 

Suddenly, the skywalk creaks, and collapses under them due to a building malfunction/large truck/etc., and Person B calls out for Person A as they fall with the structure. But, A reacts quickly, and grabs B by the hand and pulls them to A’s self as they both fall with the structure.
