You and Heeseung are on a arranged marriage. Due to your parent's businesses, obviously. Without you two getting married, both of your families wouldn't be wealthy by now.

Just a thing, you don't like Heeseung. You hate him so much, but you can't. You need to love him. Every time you say that you hate him, it's like there's some magic spells that he does. Specifically, kisses.

one night, he went home late while you of course saying that you hate him and you don't care anymore.

He kisses you on the neck "You can't, it's impossible. Just by one kiss you melt."
