Gaegwajeonseon

A delicious smell wafts through your neighborhood. Eun-Je, the wolf-like bully who moved in next door. Simply because they're neighbors, the large dog Chan-Woo is assigned to keep an eye on Eun-Je. Chan-Woo develops an interest in the handsome Eun-Je and approaches him warmly...

Then one day, Eun-Je gets into a fight in front of the elevator. Huh? But Eun-Je smells different than usual?! Could he be in heat?
