The story was well written.

Reality bites when it comes to bullying, wealth and pressure.

The cast were well chosen and justified their characters. Kim Sejeong was so natural to the extent that you don't realise she is actually acting.

The supporting roles are perfectly chosen. From the principal, parents, students and teachers.

I was just lost on the story of JDY, I felt like they wanted it to be a love triangle but failed to cross the line.

The whole story was well delivered until the ending. Worth a re-watch.
