Why do we flock to stories about forbidden love? Psychologists and narrative theorists point to several reasons:
Series like Game of Thrones (Jaime and Cersei) or Flowers in the Attic use sibling or quasi-incest to provoke revulsion — and fascination. These are the most extreme “prohibido” storylines because the prohibition is almost universal.
Studies have shown that when parents or authority figures interfere in a romantic relationship, the couple often feels more committed — not less. This reactance theory explains why obstacles intensify passion. In fiction, watching lovers overcome barriers gives us a vicarious thrill.
It is useful to acknowledge a danger of this trope. Modern storytelling often romanticizes toxic dynamics by dressing them in the language of prohibition. A relationship that is genuinely harmful—based on manipulation, violence, or a massive power imbalance—can be misleadingly packaged as “forbidden love.” The critical difference is the source of the prohibition. If the barrier is external (a rule against a healthy relationship), it is tragic. If the barrier is internal (one partner’s clear lack of consent or safety), it is not romance—it is abuse.
The Prohibition: A relationship between a high-profile client and a professional bound by a strict code of ethics (e.g., a therapist and a patient, or a lawyer and a client). This is "prohibido" because of the power imbalance.
Literature is filled with iconic forbidden relationships. Each one uses a different type of prohibition:
| Work | Lovers | Barrier | Why It Works | |------|--------|---------|---------------| | Romeo and Juliet | Romeo (Montague) & Juliet (Capulet) | Family feud | The ultimate tragedy of youth versus old hatred | | Wuthering Heights | Heathcliff & Catherine | Class & revenge | Destructive obsession that transcends death | | Anna Karenina | Anna & Vronsky | Marriage/adultery | A woman’s ruin in aristocratic Russia | | The Scarlet Letter | Hester & Dimmesdale | Religious law | Hypocrisy of Puritan society | | Brokeback Mountain | Ennis & Jack | Homophobia | The heartbreaking cost of closeted love |
Each of these stories remains in print and popular culture because the prohibition is not just a plot device — it’s a mirror held up to society’s flaws.
