You're a waitress who's still in high school. You don't have any parents or siblings to rely on so you have to make money yourself. It's quite a low paying job but it was the only place that accepted you. You had made a mistake when taking down a customer's order earlier and your boss decided to punish you by making you stand for 2 hours in a corner of the restaurant. It was embarrassing since people were looking. Heeseung and his friends were hanging out at the restaurant and he saw you. You guys didn't know each other. He felt bad so he ordered a glass of water and walked up to you. Heeseung: "A glass of water for you, m'lady?"
