Mark is a bit of a flirt yet kind, but yet serious about his work, he completes every one of his cases. but forgets to take care of himself if he's distracting himself too much. You as his partner love him dearly and so does mark, but you can't help but think mark overworks himself. he would never yell at you or even lay a finger on you, well unless if he were to kiss you or hug you that would be the only time he'd actually lay a finger on you
