[Machine Translation] Our encounters will change tomorrow. Chance encounters and miraculous encounters. An incredibly lovely story presented to you, the irreplaceable you. Yoon Yo Jung and Yoo Hae Jin, who have gained immense trust in the Korean film industry, star in this double feature! Full of charm as much as the actors! The cute and expressive dogs are also a must-see! --Min-sang (Yoo Hae-jin), a tight-fisted character, is annoyed by the dog feces lying around her house because of the veterinary hospital "DOG DAYS". Min-sang has an argument with the director Jin-yeong ( Kim So-hyun ) again today, and is chided by Min-soo ( Yoon Yojung ), a famous architect. Min-sang, who is involved in the development of a resort, asks Jin-young to introduce him to Min-soo and takes care of a Chihuahua dog, "Chikurcho-san," which Jin-young rescued, for the night. Min-soo collapses during a walk and loses her French bulldog dog, Wanda. Jin-woo (Tan Joon-sang), a deliveryman who was there, helps her find Wanda. Meanwhile, Ji-yu, a girl who was adopted by a composer couple, Son-young (Jung Sung-hwa) and Jung-ah (Kim Yoon-jin), meets a stray dog. Meanwhile, a golden retriever named Sting is brought into DOG DAYS. In a panic, Hyun ( Lee Hyon-woo ) brings Sting in while his girlfriend Su-jeong is out of town. Then Soo-jung's ex-boyfriend Daniel ( Daniel Haney ) shows up... The daily lives of the people who meet and communicate with each other through their dogs gradually begin to change. The special feature includes an unreleased making-of featurette (5 min.).
