It was a pretty good movie, with a lot of suspense that had me wondering who the real killer might be until the time of the revelation.

I liked the main characters as well; the number one student of the class and the quiet, mystery-lover girl who goes unnoticed most of the time. I found it a bit strange though for the two of them to remain as calm and collected as they did when they found their murdered classmate. Also, it was a bit strange for romance to be developped under such circumstances, but I kind of liked the interaction between them.

The supporting characters were also nice. From the teachers who knew nothing (or everything) to the friends who decided to help (or just scream at the sight).

All in all, it was an enjoyable movie with a few weak parts, which don't hinder the mystery whatsoever.

A movie I shouldn't have spent my time watching. Predictable plot and I didn't like the characters.

What I also hate is the unnecessary love lines in a movie. Did both of the main leads really have to end up liking each other? Or first of all, did Kang Sora really have to play this girl who is weird , but all of a sudden she's unexpectedly 'pretty'? It would have been better to focus simply on the mystery of the murder than adding other things into it.

Ha, I guessed the killer right from the beginning. I clearly watch way too many procedural shows, I just picked the most random person they happened to focus on.
It was still entertaining and the two leads were good, way too many people stomping all over a crime scene if you ask me, though. :P

The only parts that made me sit on edge was the "cat & mouse" game towards the end...
haha other than that, this was exceptionally an interesting film.
idk i really enjoyed watching this XD
