The romantic drama ‘Do Deewane Seher Mein’, starring Siddhant Chaturvedi and Mrunal Thakur, has posted underwhelming box office numbers, managing only Rs 6.22 crore net in its opening week. Released in a market currently dominated by high-octane action films, the movie struggled to pull crowds, peaking at a single-day collection of just Rs 1.5 crore.
