TV’s cutest siblings are back! Last season, Kim Ah-yoon and her three siblings went to a small country town to spend some time with each other. The city kids did what they could do only in the country. Children, who are 3 to 9 years old, got along together and made fond memories. Now, in the 2nd season of ‘4 Siblings’, kids are back in town to experience the fall in a rural village. They play, fight and laugh each other. The show will melt your heart once again with the kids’ making memories and growing up together.
