Reception
It is regarded as the biggest fiction launch of 2014. It ruled the 8 pm prime time slot with 7.3 TVM on its launch day becoming highest opening of the year. The show was earlier named as "Mera Nikhatoo" but it was changed at last minute to "Tu Mera Hero". The show is set in Mathura of Uttar Pradesh. This show is a tribute to Dilwale Dulhaniya Le Jayenge. Shashi Mittal, co-founder and director of Shashi Sumeet Productions said, "DDLJ is the biggest ever celebration of love and I am an avid fan myself. We wanted to pay a tribute to this story in our own way." However, she clarified, "By no means is this a copy of the film, but is a story of a girl whose life is dominated by the spirit of the film." Sumeet Hukamchand Mittal, co-founder and director, said "This story will be a tale that everyone will be able to connect with." Before and during the course of the show, 10 directors were changed in 5 months.
Mishap
The shoot of the show was disrupted after a fire broke out on the sets in Mira Road in December 2015 due to the air conditioner duct which got congested, because of which the fiber material caught fire. Luckily, none were injured.
