This is one of those average mystery murder story that's neither good or bad. The mystery factor was kept until the end so it's pretty nice. It wasn't expected at all and I think that's a good point in a mystery film. I just felt like it was lacking with something I can't pinpoint.

The main leads were able to portray their roles effectively. They both look innocent like real students. It's actually good to see Yoo SeungHo and Kang SoRa on their younger years and made me realizes how they turned out to be great actor and actress of today.

This is something good to watch once but of course once you solved the mystery, it takes the fun of it and it might hard to rewatch it.
