Heeseung was your childhood bestfriend, you two are always together, you two are so close to each other that you can't be separated anymore, only the two of you understand each other, when you're sad Heeseung always finds a way to make you happy, you treat him like your big brother

Now that you guys are old enough, both of you have gotten so matured but your treat to each other hadn't changed it's still the same how you two bond together when you were still kids, Years had passed already, you're 18 and Heeseung is 20 (he's two years older than you)

You always thought that Heeseung's maturity is really in another level maybe because he's 20 years old already, Something new to you and not only that, You also noticed that there was a slight change in his treatment of you, he acts like a possessive boyfriend to you sometimes when he sees you with another man or even a woman

"I don't know why are you acting like this, first of all I don't owe you can explanation, because you're just my f-" you got cut off by him not letting you finish

"say friend I dare you." He said coldly and a hint of frustration on his voice
