Your best-friend's name is Jung Eunmi. She lives in Seoul as well as her older brother, Junhyun, and her parents. You guys have been best-friends since you met in Kindergarten. One day in the fourth grade she showed you a picture of her family. Strangely, you couldn't find the difference between Eunmi and Junhyun. They looked exactly alike. From that moment on, you decided to call her, Daehyun. As you grew up, the nickname stuck. On your phone she'd be listed as Daehyun, as well as your occasionally greetings when you see her in school. When you begin dating, would this become a problem for you?
