It's a sad truth which many of us won't agree. It's painful but yet beautifully scripted because it's love living through life. You love her and she loves you which is good but knowing she is not yours and he is not yours, you still choose to love which is great and only some people can do.
Even if Jaanu and Ram meets in their 70's they can live together if situation is favourable. U live all your life studying, work, family, responsibilities, sometimes all you want is being with the person whom you love most, where u feel special and happy which you don't get by spending billions. It's a special feeling ...
Hope to see Jaanu 2, if possible ...
