From the first episode, it reveals they knew each other prior to the show. It also revealed that Jerry had a minor crush on Kim, but didn't lean towards it. In the second episode, Jerry is revealed to no longer have a crush on her. It is true that they get along fine with each other, hence Kim getting mad at him, and they've worked together to solve many things.
They are good friends. They have a strong relationship, which gets put on the line sometimes, but they always come through for each other towards the end. They're not the closest, but they still care immensly about each other and will come to the rescue whenever the other needs it. They help each other out in anyway they can, and tease and insult each other at times. They've dated briefly (even though it wasn't intentional for Kim) and have gone a date together a restaurant. The pair have a comfortable relationship with each other and are very open minded with one another. They fight sometimes, that's for sure, but they alway make up in the end. "Kerry" can also be an opposites attact pairing since they act so different from each other. They'll be there for each other no matter what and they have each others' backs.
In many episodes, they are seen opposite sides of each other or beside each other. They're opposites, one likes trouble, the other solves problems. One is an extremely good dancer, the other isn't. But even though they're opposites, they always seem to find a work with each other. Whether its helping one get out of trouble, or helping one with a date. They insult each other at times, and Kim physically hurts Jerry a variety of times. They have a good friendship and they don't let a small mistake terrorize it.
They know a lot of things about each other, embarrasing things, but they don't threaten or blackmail one another. They are seen glancing and smiling at each other, and they both make the funniest jokes. Whenever Jerry insults Kim, she is seen a little hurt and slightly offended, and vice versa. In Two Dates and a Funeral, Kim creates a bracelet with the letters "J + K" on two beads (intentionally for Jack). After she denies its for Jack, Jerry asks if the J is for him. Kim says yes and Jerry smiles happily, letting her know they're going on a date. Even though in the end Kim reveals the truth, she promises to let Jerry dump her infront of a bunch of cheerleaders, to make him feel better about they're breakup.
They're definitely not the closest out of them all, and they definitely don't have the best relationship, but they almost help each other in any way they can and work together to solve things. Kim often grows angry with Jerry whenever he doesn't cooperate, but always finds a way to convince him to do so. This pair shows that even though they don't act like it, they care immensly about each other. They try not to get each other in trouble (but sometimes they do & regret it) and they have each other's backs.
Dynamic

They tease each other at times, and try to make things best for each other. When Kim grows angry or upset with Jerry, he is also seen offended and hurt by this. Whenever one of them is happy, the other one usually responds with the same attitude. They argue sometimes, but they end up making up in the end. Kim, at times, also grows annoyed when Jerry tries to flirt with a girl. Since they're close friends, Jerry doesn't try to flirt with Kim. Also, when Jerry thinks Kim likes him (Two Dates and a Funeral), his expression appeared to be excited, and he casusally tells her that they're going on a date. The pair have a strong relationship where when something big happens and they turn away from each other, they always end up forgiving each other in the end, they end up apologizing and forgetting that it happened.
