The four members of Little Forest gather and meet each other for the first time. During a month before officially meeting with the kids, the four uncles and aunts study hard to learn more about children. The day has finally come and they all greet the children one by one. Will the little kids fall in love with their new guardians in the deep woods?

The first official day at Little Forest begins and everyone gets busy. So Min and Seo Jin busy themselves in the kitchen, while Seung Gi and Na Rae guide the kids to the small animal barn. From putting sunscreen on the kids to helping them finish their lunch, nothing comes easy.

After a satisfying dinner with Seo Jin’s hamburg steaks, the kids continue their adventure in Jjigbaggol. The sun goes down and bedtime comes around. However, despite their long day, the little kids can't seem to go to bed right away.

It’s the final and second day with the little kids. Everyone gets up and enjoy their breakfast cooked by Uncle Seo Jin, but it starts raining. As the drizzle continues, the little ones dress up in boots and raincoats. They come out to enjoy nature as it is and get wet for fun. Meanwhile, Yi Han contemplates hard on whether he should pull his tooth or not.

After another week, the children arrive once again to Little Forest. Although it’s been a while, each of the children are eager to meet up and greet their new friends. Right when everyone was all gathered up, a new face appears to the grounds of Little Forest. It’s Jeong Heon, a six-year-old who loves to play hide-and-seek.

The kids have fun playing with red clay and familiarize themselves with mud. Yi Hyeon, who once used to tiptoe on soil, has a total blast barefoot. As the next day begins, Grace, who’s always bright and lively starts crying. She starts finding for her mom for some reason.

In this week’s Little Forest, the little kids go to a valley where fresh streams of water flow. Before heading out, Uncle Seo Jin cooks up some cauldron chicken soup and the kids get to see a fire show.

The little kids start off their apple farm journey by learning how to pick apples.

Still remembering his humiliation from the recent bread-baking experience, Seo Jin clenches his teeth to succeed this time no matter what.

The little kids meet infant puppies who need care while briefly being separated from their mom. From feeding the puppies to wiping off their poops, the little kids learn how to be caregivers themselves.
