Trust me! I have never been moved this much by anything so far in my life and the plot twist at the end explains everything that the story has been trying to tell you. One must watch this at least once in their young times to understand more about the meaning of real life. I couldn't end a single episode without tears pouring out. I now really wish that I could have spent some more time with my grandparents and tbh I am scared thinking about what is coming next. 10/10 and is not advisable for soft-hearted people!
