Unfortunately, this remake failed to deliver the sweet cute chemistry and heart that the original C version did.
I loved the C version and was so excited that they were going to remake it in Korea, but I think they really miscast this. And the director did a poor job of giving the story some heart instead of the typical cringeworthy deliveries.

The main problem was the FL. She was trying too hard to appear young. If you ask your parents to give you an impression of a 3 year old, I bet it would be the same as the FL's acting. No idea why they casted her as there are a lot of other actresses who have natural aeygo that could have played this role. And then there's the problem with the ML. He looked too young and did not make me believe he was the smart studious type. And together, frankly it was clear that she was the nuna and he was the dongsaeng which makes it hard to believe in their characters. They pretty much had zero, if not almost uncomfortable chemistry for most of the drama. It wasn't until the very end that it got a little better and I think a large part of that is because the FL dropped the whole toddler act. To be fair, I do see potential in both of them...I just think they need to take baby steps instead of leaping to fill shoes that are too big.

I also thought the 2nd ML did not have any charm. I didn't find him very likeable where in the Cdrama, I would go back and forth between the male leads. Even if I didn't compare to the original, I would not have liked this drama. It's way too cringeworthy. I had to skip a lot of the scenes that made me want to vomit. It's interesting though because the script is almost the same and I did not feel that way at all with the Cdrama which I've watched a few times. Amazing what miscasting and bad direction can do.
