I've only drawn him once, but I'm obsessed with short-haired, bearded Kim. Expect more.

I'm thinking Kim might be a stress smoker. And he knows he's only got a few more years to live so why not, right?
Elly'd be constantly snatching it from him and putting it out like "you know its not good for you! and we both know it doesn't actually help your stress" and then help get his mind off of it
