Description: The fourth book in the 'Woongjin Blue Classroom' series, written for 2nd, 3rd, and 4th graders. This series—including previous titles such as , , and —has received great acclaim with each new release. Author Lee Sang-kwon has previously explored ecological themes rooted in our everyday reality through stories like , , and . In Gojae's class, there's an unusual boy named Seungjun. Said to have autism, Seungjun spends all day at his desk drawing pictures of bugs. The other kids tease him, calling him 'Bug Boy,' but Seungjun doesn't seem to mind—he simply stays in his own world. Meanwhile, Gojae is a spirited girl who can outplay the boys at soccer and never backs down in a fight. One day, Gojae happens to follow Seungjun up the hill behind their school, and the two finally talk for the first time. As Gojae grows closer to Seungjun, she begins to drift apart from her old friends. Using the everyday setting of a classroom and the simple motif of a caterpillar, the story builds quiet tension around a situation that could happen anywhere. It thoughtfully portrays children who understand what true friendship means in their heads, but struggle to put it into practice—capturing both their inner conflict and growth. The illustrations, which vividly convey the characters' personalities and emotions, are a wonderful complement to the story. ◇ The Bug-Like Kid ◇ A Caterpillar Eats a Caterpillar ◇ Why Can't I Be Friends with Seungjun? ◇ Seungjun, Who Raises Caterpillars ◇ They Say Han Go-jip Is Dating Bug Boy! ◇ A Bug for a Birthday Present?! ◇ Let's Fight, You Jerk! ◇ Teacher, Seungjun Wet Himself! ◇ I Caught the Caterpillar
