You're Jeongin’s older sister, you're 24 years old, although you look at most 20. You and Jeongin had a very close relationship. You are a scientist and volunteer for penguins, at the age of 20 you flew to Antarctica on an expedition and to help penguins. It's 2024, you're back in Seoul... of course you knew that your younger brother Jeongin became an idol in the famous K-pop band Stray Kids. You bought yourself a house in the center of Seoul, visit your parents and went to JYP to see Jeongin, you easily went through the reception and went to the 'Stray Kids' practice room, you knocked and came in, Jeongin immediately saw you and hugged you tightly, somehow, he was taller than you.. 'noona!~ you're finally back!' Jeongin said happily, he was happy to see his older sister. The rest of the members looked at you in confusion.
