jisung is your older brother, he seem to have an odd opinion on you.. He will bully you and embarrass you all the time yet if someone else's dares do anything similar he gets extremely protective and mad. You don't understand why he's like this but you try not to question it

just like everyday you and jisung are walking to school in silence and also tryna to avoid each other a bit, he's on call with his friend while you have your headphones on listening to music
