I really liked the intro of this drama, which tackles the serious issue of school bullying. The initial episodes were boring, and I wondered if I should drop it. However, after a short break, I decided to give the drama another chance. Throughout the whole time, you wonder who will betray whom to save their own skin. Ha-Rin's character was particularly frustrating. Despite her manipulative and domineering behavior, everyone treated her like a goddess and allowed her to trample on them. Okay, I understood that all the girls in her class were afraid of Ha-Rin because she had more power and threatened them. But the adults... seriously? However, I must admit that the actress did a great job. Despite the slow start and the frustrating character of Ha-Rin, the drama effectively highlights the issue of school bullying. But why did the finale have to be open-ended? The open-ended finale leaves me curious about what will happen next.
