The plot is nothing new; it's about high school bullying & revenge. But how it's executed and performed by the cast is more to be focused on. After watching Part 1, I loved the cast acting, mainly Song Hye Kyo, Im Ji Yeon, & Park Sung Hoon. They've protrayed their roles perfectly.

The story may seem slow at first, but when Moon Dong Eun starts her revenge plan, it gets exciting. 

Moon Dong Eun is strong, smart, confident. She worked hard to reach her goal. 

The shock face of Park Yeon Jin after seeing Moon Dong Eun after so many years with full of confidence. Hated that homeschool teacher who only supports rich kids.

I was so satisfied when Moon Dong Eun pulled off Lee Sa Ra's hair.

It’s funny as well as cute how Joo Yeo Jung shouted after seeing Moon Dong Eun message and kept on guessing weird stuff like marriage, divorce, & remarriage.

Loved Kang Hyun Nam; she is clever and knows how to use her cards. She is a victim of domestic violence but not a timid person. I loved how she cares for Moon Dong Eun & helps her in every step.

Loved how Joo Yeo Jung accepted Moon Dong Eun injuries & didn't pity or feel disgusted with them instead joined her in her plan.
