Varun Dhawan and Alia Bhatt share a great relationship with each other. They made their debut as actors in the film industry together with Student of The Year (2012), which is also getting its sequel Student of The Year 2 (2019) starring Tiger Shroff, Ananya Panday and Tara Sutaria. 

Karan Johar has been mentoring his proteges, Varun Dhawan and Alia Bhatt ever since Student of The Year. From choosing the right script to moulding them to stars, he has been the right guide to them. During this process, Varun and Alia individually developed a special bond as they went on to do films like Humpty Sharma Ki Dulhania (2014) and Badrinath Ki Dulhania (2017) after Student of The Year, and now Kalank (2019).
