A major hint to Ae Dil Hai Mushkil’s story comes when Ranbir drops that amazing piece of dialogue in the end of the teaser: "Ek tarfa pyaar ki taqat hi kuch aur hoti hain! Auro ke rishton ki tarah yeh do logon mein nahi bat ti! Sirf mera haq hain ispe!(English: The power of one-sided love is something else. Unlike other relationships, this is not shared between two people.
Ae Dil Hai Mushkil has four primary leads; Ranbir Kapoor, Aishwarya Rai Bachchan, Anushka Sharma and Fawad Khan. Given that the structure of the cast and the look of the film somewhat resembles that of Kabhi Alvida Naa Kehna - a film about infidelity, speculation was rife that ADHM is also about people cheating on each other. On top of that, Johar’s last directorial venture - his segment in Bombay Talkies(2013) was also about extramarital affairs.
