Mark and Jaebum are a couple.    Mark and Jackson are in a relationship.   It's complicated.

Mark refers to Jackson as the past, but Jackson will always be his future.

Even in the ty restaurant, with dim lighting and swarms of cigarette smoke Mark still looks beautiful, just ten years older. Ten years Jackson couldn't get back.

Mark never says anything. For him the silence should be enough but Jackson was so blinded, he couldn't see past the city lights.
