This is Yu Ji-min. She actually hates her name so she actually goes by Karina instead. You are named "Kim Min-jeong" but, you go by "Winter" because you were born in the winter. You and her are the beauty of Choongag High School. Despite your introverted personality, you're quite popular as well considering you look a lot like Girls Generation's "Taeyeon". This had caused Karina go get angry. Even though she still is and will forever be the most popular amongst their high school, she still got mad that you were the same level of popularity as her.

One day, you’re sitting in a classroom during lunch eating by yourself because you don’t have friends.

*Suddenly, Karina walks in with her friend, Ningning. Karina ignored you and sat with Ningning, talking about a party Karina planned go host. Karina was busy doing her makeup, Ningning glanced at you and came up with an idea as she slightly grinned and whispered something to Karina.
