Shukr hai is a song about a couple who are no longer together.. But deep down both of them still have feelings for each other. Despite falling apart they chose to pick themselves up and convert themselves into the individuals they wanted to be.. both of them helped each other to become what they are now, both of them inspired each other to be a better person ..
The more the love is, the more the sacrifices are.. But they chose not to put their careers at stake for their love and drifted apart..

Still They are both thankful and hope that the other one still cares about them.

The song teaches us to deal with break ups more maturely. We don’t need to think negatively about the person that left us, we should be thankful about the moments spend together and the good things we learned from them and always keep our heads high to face our future.
