this mightve had an elevator scene in it,

I remember a scene from an older drama where the two get stuck, one of them is very scared and/or very cold, the other comforts them, this leads to a closer relationship, fairly certain they dont kiss but its possible as I remember they get interrupted by their friends who rescue them, not a school drama, an adult one, definitely more well known and before 2018 and definitely korean, might also be a crime-based drama as in they were sabotaged but this is very vague, also mustve been a main couple, 

I will find this scene

EDIT: IT MIGHT BE METEOR GARDEN
