"After a long time we have seen a good love story. If people think that it is a light rom-com, it is not, it is an outstanding love story," Kunal, who saw the film at a special screening Thursday, said.
Kunal is impressed with all the performances and had a special word of praise for Ashutosh Rana.
"All the artists have done a brilliant job, not just Varun and Alia. Ashutosh Rana has come into a film after so long and (what a) fantastic performance. Everybody in the film has performed brilliantly. Claps in a trial are rare but this happened between scenes," he said.
Kunal added: "It is a very intelligently written film. It is very tough to write such a film and like I said, it is a love story after a long time and not a rom-com."
"Rom-coms run for a few days but love stories run for many weeks so this is a very big hit," he added.
