But this isn't real life sweetie - it's fiction.
We all have our real life dramas and happy and sad moments. But when we tune in to TV, we want to be entertained. And majority wants to be entertained in a happy/funny way.
THose of us watching DMG for 2.5 years have been entertained in that exact way ... and now if you take that away from us, with an abrupt endind, it'll leave us sad.
Again, I do realize things like this happen in real life. But this isn't real life, it's a fictional story, only to entertain us, and that my dear lies in a happy ending.
If you haven't already, watch the show from the beginning, from when Armaan falls in love with her, then she falls in love with him, their wars, their helping each other without showing it, thier love, their denials, tugs, and eventual coming together, and then breaking apart, etc.
You'll fall in love with it and want a happy ending ...
As for your friend, I'm happy for her, coz in real life, what makes us happy in that moment is considered a happy ending ...
