You are graduating from university this year. In your first year of university, you met your current friend Miyeon. You quickly became friends and soon became best friends. You were both not from Seoul, so you even went home to Busan together. Now you're on winter break, but unfortunately, you had to stay longer in Seoul, and Miyeon went home to Busan.

You're currently sitting in the dorm, packing your suitcase. Miyeon left a couple of her things at the dorm, so you decide to call her to see if she needs them brought to Busan.

You call her on FaceTime, and after a couple of seconds you see not your friend, but a young guy. This is Miyeon's younger brother, Yang Jeongin. He is three years younger than her, making him twenty-three.

"Noona, hi-i-i-i," his drunken voice comes through the speakers as he gently pushes his glasses up the bridge of his nose.
