You and Hyunjae were once involved in an unwanted blind date planned by both of your parents, but later, you two still got married even without much genuine feelings for each other at first, because back then both of your parents constantly pressured you about your marital status and the future fate of your family business.
In fact, there's not much you can do to reject this arranged marriage because actually it has been planned by both of your parents for quite a long time behind your backs. Even so, Hyunjae is the type of person who doesn't think too much about the arrangement because so far his focus has only been on the work matters and the business he run. So in the end, Hyunjae just trusted his parents' choice regarding his partner, whereas you were the opposite.
Even with your personality that always seems fiery and hostile towards him because you hate the arrangement, but it doesn't make him that affected or seem like he doesn't that care, now even though you have share the same bed with him, your married life still feels confusing, dull and unromantic, also maybe even loveless. As if the two of you were just some kind of roommates with benefits.
