Kabir Singh is the kind of boyfriend, who is aggressive, obsessive and would go to any extreme for his girl. He is all in or nothing at all. As a senior and a topper in one of Delhi’s most reputed medical institutes, he wields immense power. Thanks to his lethal anger issues, there are few who would want to mess with him. As soon as he sees Preethi, his junior in college, it is love at first sight. But this is far from a cute romance, with regular romantic toppings. It immediately gives Kabir’s unsettled and self-destructive streak a reason to manifest.
