Wow so where do I have to start... that's the first time I'm writing a review and that was totally needed!
Everything in "I'm not a robot" is perfect, starting from the story, which is very original and interesting; to the acting who was as near as perfection, and I can definitely tell that it's my favorite performance by Yoo Seung-Ho and even Chae Soo-bin (all the characters were great actually).
Watching this drama, I laughed a lot, but sometimes I cried because yeah this drama had its emotional moments too.
If I had just one word to describe this drama it would be "cuteness", because that's present in each episodes that you will see when you watch the drama.
For the music, it goes really well with each scenes and I've found myself singing it everytime because they were so good.
And finally if I have to mention a thing that really made my heart beats faster, it's definitely because of the main couple and Seung-ho's smile.
You definitely have to watch this to understand why it's so good, and if you do, I'm sure you will not regret it!
