Sunwoo looks like a harmless little puppy on the outside, but everyone in the office knows he's more of a feisty cat—sensitive and aloof, through and through. Hyunjin, on the other hand, is like a big friendly dog—always ready and oh-so-eager to befriend Sunwoo. After his fruitless efforts to avoid Hyunjin within the office, Sunwoo gives him an ultimatum that results in their unlikely new friendship. Rocky roads await the puss in suit and pup in tie!
