The mystery and investigation isn't the main ingredient of the story. They're just a part of it. It's more on psychological or mental. The story obviously doesn't cover the entire suicidal people, but it offers you a look at the process. It gives you opportunity to have a look into their hearts and minds.

This movie will tell you how suicide is not simply about a person taking his/her own life. It is not a hardcore psycho you might be expecting but it's a different type and it's beautiful.

I love how the story happens in just one room which makes you curious about what it has to offer considering the limitation of the setting.

Each character is unique giving different flavors to the story.

Watching this with an open mind will make you even appreciate this more.

ps. the casts are all eye-candies like WOW what a bonus! ><
