★Korean Rising star author Je, Seong-Eun’s 3rd book! The author's prequels had been sold to Japan, Taiwan, and Russia!
★Dealing with online review and rating system that prevails in our digital society.
★Thinking about the social network’s power to give good and bad ratings and its side effects.

A star-rating system is a convenient way to get customer feedback on a product or service. New customers rely on them when choosing a restaurant or hotel, and merchants use high rankings as a marketing tool. However, there are increasing cases where the star-rating system has degenerated into power and caused damage. In extreme cases, low-rating reviews have resulted in store owners having to close their businesses. Is there another way to stop this and provide fair feedback to both customers and sellers?

★ is a story about star- rating notes that occur in classrooms, and raises questions about the positive functions of the star-rating system and the problems that arise from it.

It was a big surprise that Ejun was elected as student president. In fact, the leading candidate was Arin but he got higher ratings on a mysterious ranking note. The small kiosk Ejun’s father runs became high-ranked at a gourmet rating but suddenly got the worst review and lost customers as the result. Now Ejun starts investigation for who is there behind the rating system.
