Classroom 1, Grade 4, Baekwoon Elementary School. Today, Younghoon is in an eraser-eating contest with Kangsan. Despite his hard practice, Younghoon loses the eraser to Kangsan’s stubbornness.

With a glimmer of hope, he tries to compete again, but Kangsan takes that eraser away from him through a dirty trick.
