Overview
Two men, Tommy and Si-woo, fall in love with the same woman and eventually find out that she is a two-timer, so they join forces and succeed in getting revenge on her through sex, and the two become close friends. As time passes, they also let their sister-in-law become their sex partner; that is why they call them puppies, or rather, love dogs.
