There are many things I feel compelled to discuss regarding this series. However, let’s be brief. This drama, which deals with bullying in schools, produced conflicting emotions within me. It was unsettling and disheartening to consider that instances of bullying might be increasingly prevalent in certain areas. While I believed the situation wasn't severe where I live—or at least, I had thought so. This bullying appears to be a long-standing, concealed danger, like just the surface of an iceberg. However, what’s become clear is that recent incidents of bullying have been truly shocking. It seems as though the emotional toll on those targeted isn't being adequately addressed. Those responsible can move forward with their lives, but for the victims? Life feels burdensome. It’s a complicated experience, but conflicts between students, violence from teachers toward students, animosity from students towards teachers, and even accusations leveled by parents against educators all exist—and will persist if we fail to restrain ourselves. This drama seems to expose these realities (even though it's presented within a fictional narrative). Beyond the bullying aspects, I genuinely appreciated this series, particularly the exchanges between Na Hwajin and Minister Choi. The understated, paternal humor was also quite amusing, prompting me to laugh on multiple occasions. Regarding the performances, I believe everyone involved deserves recognition. This drama is truly exceptional; it’s a perfect combination.
