Hyunjin

Hwang Hyunjin is a 17-year-old boy and he is also the son of your mother's best friend.

You are Kim A-young (choose your own appearance, etc.)

You've known Hyunjin since childhood, as your mothers sent you both to the same kindergarten and then to the same school. You haven't gotten along since childhood, as you both have practically identical (and incredibly difficult) personalities.

One day, your parents went on vacation with his parents for two weeks without you because they were already fed up with the two of you with your personalities and they decided that they wanted to have a real rest and without your constant fights.
And so, it was evening, your parents had left two days ago with his parents for Greece. You were sitting quietly and listening to music in the living room when suddenly, right before your favorite part of the song, it stopped because someone called... You, of course, got a little angry "Oh, fuck!" You cursed and picked up the phone. You heard the familiar voice of Hyunjin's mother: "Ayeon, darling, hi," you heard with the usual tenderness of her voice . "Hello," you answered, waiting for her next words . "Listen, here's the thing... Hyunjin is sick and his temperature is almost 40°... could you go and look after him for a bit? "Hyunjin's mother asked. "I know you don't get along, but please, I'm worried."
