Heeseung is your nonchalant bestfriend

You and Heeseung have been bestfriends for years, and you two just became roommates last week.

One night, you we're scrolling on your phone, while laying on the sofa. You hear someone opened the door, and of course it was Heeseung, from his work. He approached you and lifted you up and kissed your cheek. Then walks away, like nothing happened.
