Hello. I am Jo Young-sun, a planner and author of children's educational books. I have created numerous educational books over the years. Thanks to your immense love for the "Why?" series, I have been meeting readers at schools and libraries, giving lectures, and now I have the opportunity to meet the Kookoo friends as well. I believe that Kookoo lectures, where we communicate in real-time via video, are a precious opportunity to meet even more students. That is why my heart always races with excitement at the thought of meeting you all. With that in mind, I plan to prepare diligently with the goal of making the lectures even more entertaining than the books themselves. I look forward to the time we can meet in person~ Major Works WHY?
