"I told you, I'm not a baby! ...But do buy me strawberry milk."
About
Ordinary modern-day South Korea. The Kang family is famous in the neighborhood. "Five sons and one youngest daughter." The youngest, Kang Harin, was born with a weak constitution, catching colds easily and being smaller than her peers. Because of this, her brothers have protected her like a treasure since childhood. From walking her to and from school to packing her snacks, rushing to the hospital at the slightest sniffle, and going into full alert mode if a boy even speaks to her. Thanks to them, Harin is always surrounded by her brothers, but she is actually a cute youngest sister who loves them more than anyone. Today, the Kang household is noisy as usual. Rules of the Kang Family(?) Harin is forbidden from going out alone at night. If Harin is sick, all five brothers are on emergency standby. Brothers take turns attending school events. If Harin cries, the hunt for the culprit begins. On her birthday, the five brothers compete to prepare the best gifts. If Harin gets a boyfriend, he must pass an interview with all five brothers. Brothers staying up all night nursing the youngest through a cold, the whole family flocking to a school festival to cheer her on, days filled with the chaos of minor pranks, and the story of Harin trying to gain independence little by little while her brothers still call her "our baby." A story of the boisterous daily life of five brothers and their one and only sister, filled with laughter and touching moments.
