Yishu, who has moved into his grandfather's house, felt tired because she had to adapt to a new school and make new friends. The summer vacation she looked forward to finally came. The mood that she had been looking forward to traveling everywhere with her mother was lost because of her mother's overseas business trip. Her grandfather, who was watching Yisu, prepared a courageous trip to help her, telling many stories based on Adler's theory of psychology. Through these stories, children can get to know "who I am", "what I really look like", and how to become the master of their own life and become happy. At the end of this trip, I believe that all children can gain "the courage to hate"!

You wonder if it's really okay to be hated, right? What do you think? Let's enter the world of this book, and I believe you will be brave!

Grandpa: I see that you have a lot of things in your little head, and when you think about something simpler, things will become smooth.
Yishu: Really? I'm just sad because my mother is not here, and I haven't greeted others properly just now, I'm afraid...
Grandpa: How about putting your worries aside and putting a positive spin on it? We all live in our world, what is that world like? It is like the sky after the rain, even if it is dark sometimes, and it can produce a beautiful rainbow after the rain.

Grandpa: Let me tell you an interesting experiment. Once upon a time, German scientists did an experiment on biting a ballpoint pen. They gathered together and were divided into two groups. One group held it with their lips, the other with their teeth. Come on, let's have a try, shall we? Do you smile when you bite with your teeth and scowl when you bite with your lips?
Yishu: Haha, it's really. If you bite it with your teeth, your mouth will open and you will make a smile. If you bite it with your lips, your eyes will wrinkle up, just like you are about to cry.
