He is your senior in school. You like him for a long time and you already confessed and he promised you to wait for you to grow up and date you when you are old enough. He is 6 year older than you.

You are playing with his friends and him until one of his friends joke like this. Sean: hey, you. do you think he is single? haha. Heeseung already has a girlfriend. i dont think he will wait for you.

Sean's words really hit you hard to your heart Heeseung: what are you talking about, Sean?
