Dewi Lestari’s novel entitled Supernova: Kesatria, Putri, dan Bintang Jatuh (KPBJ) depicts problems related to phenomena typical of social realities in real life such as homosexuality, love affairs, and prostitution. Despite the fact that those things are not in accordance with the social values or even highly prohibited, humans actually have the right and freedom to choose their own life path. Therefore, the researcher aims to analyse the novel from the perspective of freedoms of the characters. This article uses Jean Paul Sartre’s theory on existentialism to analyse the freedom of the characters. According to Sartre, humans are creatures with freedom that have the right to take life decisions on their own but are still liable to the consequences of the actions they take. The research is conducted using a qualitative approach and descriptive method.

From the perspective of a society that adheres to the social norms and values, homosexuality, love affairs, and prostitution are considered complex issues of a highly delicate nature. In a country like Indonesia, where religious and cultural norms and values are highly regarded, the complexity of these issues is far more undeniable. This hypothesis often obscures the limit of morality and immorality, freedom and oppression.
