Everything on the White Planet is black and white. Everyone on the planet has white skin, except for Choi Min-je, who is the only person whose skin bears colour. Everyone treats him like a monster. Min-je has a violent and lonely upbringing and loses both of his parents. He believes that everything has happened because he is different. He wants an ordinary life like others, and the only way to achieve that is to get off the planet. The sky is filled with such beautiful colours. Somewhere beyond the sky, surely exist people just like him. Just when he needs them most, people who claim that they can help, show up in Min-je’s life.
