“Hey, mom.” Acorn wearing a yellow hat appears to have something to say to mom. It looks like it wants to talk about a ‘friend.’ From the strong Almond to thoughtful 
Rice and warm-hearted Macadamia that worries about friends when sick. This book talks about ‘first friends’ when our children come out to the world and make 
new relationships using cute nuts in a special, leisurely and friendly manner. Yun Jee-hoe is an author who completed and kept an eye on this book nervously while 
thinking about her only son who will continue to grow and develop. Like the Acorn in the book, he will also probably cry, laugh, console, fight, and make up with many 
friends as he grows.
