Title: 생각하느라 그랬어요
This book is very heavy in vocabulary and grammar. Not impossible to do, but definitely not for beginners despite it's over all simplicity. It's about a young boy who thinks and thinks about everything. Each time something happens it triggers an avalanche of thoughts. It's an interesting read, but save it for your more intermediate moments. This book is not available on amazon so it's a recommendation for those studying Korean in Korea.
