This is the best show I have watched this on netflix. The writers have done exceptional job in writing the story and at times goosebumps inducing scenarios which relate to one another in complete unexpected way. One more best part in the story was that the seriousness and dark mode never lasted long and when it did, it faded away with the best climax I have watched. The ending of the story is beautifully and leisurely written which just warms your heart. Each and every actor and their characters are awesome as they are done justice on till the end. And how could I not appreciate the lead female, AJI 3(robot), or Jo Ji A, is beautiful both as human and as the Robot from the start. It's a heart warming series from start till the end which will make you laugh and cry. Authors are genius to have written such an amazing series. No! It's not the plot that is fascinating. It's the little details. Every show I watch, I wish I could see a character's reaction for a certain moment. And this one Korean series fulfilled my wishes. This series has goosebumps inducing authors, amazing directors and the most beautiful actors. Minor spoiler - The Climax with meteor shower would be the most beautiful part, which I loved as an author and as an audience. It's genius and beautiful. End of spoiler.❤❤❤❤
