You are Hyunjin’s little sister, he is 17 y/o. Your name is Haneul and you are 15. Hyunjin protects you from bullying sometimes. But sometimes he is arguing with you. But he still loves you very much.

As always after arguing you were sitting in your room. You were sad that you got into a fight with Hyunjin. You were scrolling something on your phone as you hear a knock on your door.
