I watched this show after a friend suggested we watch it together. We were eating ice cream and I was pausing the episodes every ten seconds because every time I saw the main lead my heart would almost stop. His smile is heartbreaking.

I do see the flaws in the plot: unrealistic at times, inconclusive ending for some characters, the way the main lead got over things so abruptly (this is a spoiler-free review so I won't talk about it here). Apart from some plot holes, the ost was rather underwhelming. One song kept playing, over and over again. I get that's the main couple's track and the song itself wasn't bad at all. But after some time it got bothering and took some magic away from the big moments, which I think is the opposite an OST should do. The acing was great but not the absolute best. The main leads did an amazing job at the more emotional scenes though!

Although I noticed all these negative points, there's something SO special about this show that simply makes our hearts race, really. I couldn't stop thinking about it when I wasn't watching it so I watched the whole thing in two days, even finishing it before my friend who watched the first few episodes with me (which is a miracle btw).
The robot was the cutest thing ever, the female lead was sooooo likeable and talented, the main lead was so stunning and amazing at acting that I will never forget his face and name again, the side-characters and their development were great... The show was very well casted.
Honestly, some of my ratings are purely based on how many feelings the show gave me and that's okay. This is a perfect example of an imperfect drama that simply captures your heart and ends up on your top favourites list.

Definitely worth rewatching and rewatching and rewatching. I wish more people had given it a chance, it really deserves more love and praise.
