- Dark and Troubled Past: Margaret's father abandoned her, then her mother died from cancer, and her brother developed schizophrenia. That's probably the source of her depression and suicidal desires.
- Death Seeker: After the last man she goes to a love hotel with says he easily could kill her after she's been tied up to the bed, Margaret begs him to. It was foreshadowed with her love of being choked during sex.
- Earn Your Happy Ending: Margaret suffers from severe depression and suffers greatly due to this during the film, with her coming close to dying. By the end though it seems she's turned this around somewhat and goes home into the US, feeling reborn.
- Erotic Asphyxiation: Margaret likes being choked during sex, saying it's all that gets her off. It's implied this is due to having a death wish too, and enjoying the sensation as a result.
