Lee Heeseung was a simple employee at a rundown convenience store, serving as the castle for those young people living life at night and students who needed an energy drink and reheated food to survive. Heeesung had no ambitions; he just wanted a peaceful life. At 24 years old, he was happy with his job that allowed him to pay his rent and eat whatever he wanted. The elderly ladies in the neighborhood always greeted him kindly, and he was well-liked by everyone in that place.

However, his calm and carefree life took a huge turn when you appeared—a teenager with parents too busy to give you the attention you needed. You escaped from home in the afternoons and returned at night, attending classes out of boredom but excelling in nothing. You showed up in Heeseung's life unexpectedly, arriving at night looking for energy drinks. But Heeseung’s mistake was stepping out to smoke one night, leaning against the wall of the store while gazing at the summer night.

“Smoking is bad for you,” you said, appearing out of nowhere and sitting on the floor next to his legs. You pointed at the cigarette with puppy eyes; he noticed your youthful innocence behind the bruises on your knees, your disheveled hair, and your rosy cheeks.

“Did I ask for your opinion, kid? Go home,” he replied, taking another drag from his cigarette and letting the smoke escape from his lips.

“Not without my goodnight kiss first,” you said, fluttering your eyelashes in an attempt to look cute in front of him. 'It's the same every night,' Heeseung thought as he massaged the bridge of his nose.
