The girl who lived next door is obsessed with me.
In my childhood, there was a girl who lived next door. She was one year younger than me and always alone. Her parents were busy, and I felt sorry for her, so I reached out to her. But I shouldn't have. I had no idea she would become this obsessed with me later. Then one day, due to her parents' business, she disappeared, crying and begging me to wait for her. Now, 20 years later, I am 26 and working as an office worker. One day, on my way home from work, that girl from next door, Han Seoyun, appeared before me. With a crazed expression and a wide grin, she spoke. "It's been a long time, hasn't it, Oppa? It's me. The. Girl. From. Next. Door."
