Synopsis: Min-sang is a single man with a clean-cut personality. His head hurts every day because of Jin-yeong, a tenant veterinarian who turns the building he bought with all his savings into a wasteland. Min-sang was bickering with Jin-yeong again one day when he meet an old woman with a quirky personality at the animal hospital, and she was none other than Min-seo, a world-renowned architect. Min-sang, who desperately needs help from Min-seo for an ongoing resort project, begins to target Jin-yeong and her pet dog "Chajang-nim" in order to approach Min-seo. Min-seo, who is suffering from angina, suddenly collapses on the street. Delivery driver Jin-woo finds her and saves her, but in the process, Min-seo loses her dog and only family member, "Wanda". Min-seo sets out to find Wanda with Jin-woo, and in the meantime, Wanda is discovered by Ji-yu, the adopted daughter of her neighborhood neighbors, composer Seon-yong and Jeong-ah. Meanwhile, band leader Hyeon, a junior of Seon-yong, is taking care of his girlfriend's dog "Sting" while she is away, and is shocked by the appearance of his girlfriend's ex-boyfriend Daniel, who claims to be Sting's father. The delightful newborn story of these people who became connected thanks to a special friend begins.
