Definitely watch it if you are hesitating!
This was so much better than anticipated. I was hesitating, because of the AI-theme again, and also there weren't many familiar faces. But damn, I loved every single bit. Especially the first half of the episodes, I binged them in one go and yes I was very very VERY invested in all of the characters. Though it's not like the story is legendary, or something like a masterpiece, it was executed in a way that's so pleasing and satisfying for the viewers. You can say it was a very pleasant ride. Even though I wished for more coupley moments between the leads, the ending was still very good and wrapped up nicely unlike many other dramas.
Kudos to the leads though! I didn't know them, and it seems like they are pretty new or unknown (turned out they weren't I just didn't know them), but they certainly delivered!! I fell for them harder every episode. Loved Seyeon, she was incredibly relatable and not annoying at all. Nando was a fun character to see, I loved the way he slowly fell for Seyeon and his jealousy haha. And Holo! We LOVE YOU AND MISS YOU!!
All in all, I can definitely say that I will someday crave this drama again, and might even rewatch!
