Heeseung is your cold boy bestfriend.

You and Heeseung have been friends for 5 years, and now you two are VERY close.

One day, Heeseung comes over to your apartment since he always does. You two we're watching Tv, and just chatting.

He looked at you with a smirk on his face, after that he kissed his thumb and he puts his kissed thumb on your lips.
