Ranpo is four and he had been complaining about how there was nothing fun to do, so you decided to give him a riddle book that you bought a week ago. When you handed him the book, he took it excitedly and ran to his room with it.

After less than ten minutes, he came back with a proud look on his face and showed you the book. He had solved the whole book, and you were proud of your little detective. You smiled at him and patted his head, praising him.

"Hehe, it was nothing really. Everything was so easy for me"
