Liar Game.
Nice show.
Adapted from a Manga, there is an anime version and a live action version.
Watch the live action one.
10 episodes of 36 minutes and 1 episode of 2h25mins.

It's about people getting involved in a game called Liar Game Tournament, where they are to deceive and trick others in giving up their money. Apart from the very pretty main actress Erika Toda who acted as Nao, the strategies used in obtaining other people's money are very interesting. It's nothing close to using violence and robbing others of their money. Its all about using brains and the art of deception.

This show serves to remind all of us that the world is not as pure as we think it is. Not to believe in just anyone we meet and never to let our guard down or else we will be the ones at the losing end. However while protecting ourselves, we should also not inflict any harm on others.

as the chinese proverb goes, 防人之心不可无,害人之心不可有.
