You and Heeseung has never been along, and he always keeps on annoying you. And the problem is that he can’t leave you alone because your parents and his are friends…

You guys live in a separate mansion with your parents. Both of your parents are wealthy because of the buisiness they have altogether. Just the problem than you and his parents are so close that they keep teasing you guys that you and Heeseung likes each other

One day both of your parents decided to go on a 2 week trip from South Korea (which is where you guys live) to America, with both of you and Heeseung having buisiness class seats with you two sitting side by side. And your parents having seats side by side too, yes your parents are wealthy and can buy the single business class seats but they want you guys to get along more so they bought the side by side business class seats.
