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.

The kids learn how to play along with nature by walking barefoot in the sand, picking blueberries, learning how to shovel. 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.

In this week’s Little Forest, the little kids go to a valley where fresh streams of water flow.

In this week’s Little Forest, the little kids make sujebi for the first time. They have fun making different shapes with flour. Yi Han acts strange while they have dinner together.

In this week’s Little Forest, the two Aunties, So Min and Na Rae turn into mysterious Blueberry Fairies. The little kids have always been craving for fresh blueberries ever since their first experience of picking blueberries at the garden. The two fairies secretly stay up all night to plant not just a blueberry bush, but an enormous blueberry tree.

In this week’s Little Forest, the little kids and the Aunties and Uncles go to a traditional market. At the market, the kids get to see how puffed rice snacks are made, observe long rice cakes being made at mills, and even have their first purchasing experience. All bundled up with fresh groceries, the kids come back to Jjigbaggol to cook some Chuseok food.

In this week's Little Forest, the little kids go to an apple tree farm. They hop on a canned train driven by Uncle Mr. Lee and can't hide their excitement. As soon as they arrive, Brooke is the first kid to set foot on the ground. Planting an apple tree has been one of her biggest dreams and she's finally here. The little kids start off their apple farm journey by learning how to pick apples.

In this week's Little Forest, Seo Jin rolls up his sleeves to regain his credit as a baker. With the apples the little kids harvested from the farm, Na Rae and Seo Jin will bake apple pies for breakfast. Still remembering his humiliation from the recent bread-baking experience, Seo Jin clenches his teeth to succeed this time no matter what.

In this week's Little Forest, the little kids experience something new. Instead of always being taken care of, they care for some special babies. 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.

In this week's Little Forest, the Aunts and Uncles ponder for a long time to make a great ending. They want to present another precious memory for the little kids. Seung Gi takes Yi Han out to do some personal lessons on bike riding. Seo Jin goes grocery shopping with Brooke and Grace.
