P.S.: I have a doubt on which ending to choose
In modern-day Mumbai, twenty-six-year-old Karan is living a happy life until a chance encounter with Chhaya blurs the line between mythology and reality, and Gods and aliens.
Chhaya’s charm and beauty make Karan fall hopelessly in love with her. But before he can tell her how he feels, she reveals herself to belong to an alien class referred by humans as Hetaera.
She explains that thousands of years ago, an indigenous primate from Earth stopped a galactic civil war with his extraordinary abilities. To Karan’s shock, Chhaya discloses that his genes dormantly possess the primate’s power of telepathic subjugation.
As another more destructive civil war looms, Chhaya confesses about being tasked to manipulate Karan into donating his powers or helping her in finding others like him and stop the galactic apocalypse.
Shattered by Chhaya’s deception, Karan confides in his best friend. Learning about the imminent apocalypse, his friend confesses that their friendship is also a sham created to protect his genes for this exact situation, and requests Karan to help save billions of lives.
(((With everything in his life revealed as a farce, a devastated Karan needs to make a choice: listen to his heart and condemn the ones that lied to him, or ignore his emotions and relationships to save the galaxy. )))
(((With everything in his life revealed as a farce, a devastated Karan must now somehow muster the strength to ignore his pain and face the monsters that even the Gods are petrified of. But he needs to recover quickly because unlike Chhaya, other Hetaera might not wait for his consent.)))
