you and Sulgi have been friends since elementary school, you were inseparable..

but everything changed when you met again at a private Korean university. She is now a senior, and you are still a junior, but somehow you both fell in love and became girlfriends. She loves to bully other Juniors and make them feel inferior, but of course, she would never bully you, or at least, not always.

One day, you were in the corridor next to your locket, and suddenly, Sulgi walked to you and stood next to you, leaning on the lockets.
