End of a miraculous Journey

The thing about Double Happinese in its final episode is that everything just fell into place after almost a drama of 100 episodes...

However in reality, that doesn't happens, and i wonder why must the scriptwriter put everything onto place in the final episode...It simply doesn't reflects reality, thus the whole show can really be deemed truely as an end to the whole miraculous journey, indeed miraculous. I do like the part before Jiaqi collapses in the final part though

School starts finally this week...
