On the occasion of International Girlfriends Day, here's a heartwarming throwback featuring one of Bollywood's most-loved couples, Rajkummar Rao and Patralekhaa.During an appearance on The Kapil Sharma Show to promote his film with Kriti Sanon, Rajkummar was asked by Kapil whether filmmakers cast him in relationship-centric films by coincidence or because they believe he perfectly fits characters dealing with marital issues.Responding with his trademark humour, Rajkummar said that since he wasn't married at the time, filmmakers probably wanted him to understand the challenges of marriage in advance and prepare him for what lay ahead.
