Guilty of Romance (恋の罪, Koi no Tsumi) is a 2011 Japanese erotic romantic thriller film directed by Sion Sono.

[3] A grisly murder occurs in Maruyama-cho, Shibuya, Tokyo – a love hotel district – where a woman is found dead in a derelict apartment.

One day, to break away from the loveless monotony, she decides to follow her desires and accepts a job as a nude model enacting sex in front of the camera.

[4] A review on the website The Spinning Image states that 'All the way through this microscopic scrutiny of (the film's) lead character and how she reacts to this underworld(,) Sion (Sono) conjured up a variety of strange scenes designed to disturb".

[5] A review in Variety, although praising the film, states what follows:"Kafkaesque storytelling, which intertwines the stories of three women grappling with sex for money and murder, is again inspired by fact, but the feverish imagery remains the director’s own.
