strangers to friends to lovers

You are just a normal highschool girl. You're learning to drive and trying to save up for a car. So, you have a job. You work at a grocery store and have to stock shelves and stuff. But, one day, you were on a step stool, restocking the very top shelf. Until you lose your balance and slip. Luckily, there was a stranger that was admiring you from afar and got to you just in time. He caught you. His name is... Han Jisung.
