For someone who watched the original version, I can't help myself but to compare. But in this review, I'm going to limit the comparison and mainly focus in this Korean version.

First of all, as a fan of Kim Yohan since PDX101, I'm so happy that finally he made his acting debut. But tbh, his acting is kinda stiff and confusing. I understand that it is his first acting but the viewers need more than that. Poor acting really affects the whole show.
Same with So Juyeon. I love her so much in Dr. Romantic but his role here is cringe and look like she's forcing to be cute and clumsy which didn't really work.
Yep Hoe Hyun's acting on the other hand, is commendable. He's cute and sexy at the same time. Wu Busong and Woo Dae Sung, you both match and did your role perfectly.
Then we have Jung Jin Hwan. Unlike the C-version, I don't find him cute, adorable, and funny. I'm not really happy but still he did well too.
The good thing about this remake is how they change the episode of Kang Ha Young not falsely admitting that she is the one who gives the medicine to her depressed classmate. In the Chinese version, I was really annoyed by that scene.

The first part of the story (during their highschool days) is pretty boring and plain. The only reason I keep watching is to finish what I started. Thankfully, the moment they enter University, the story is getting good and I'm glad to see that progress.

The music really fits the concept, I like it more than the remake of the drama itself.

Overall, I give this a rating of 7.5 over 10. If only they manage to be consistent from the very start, maybe I can give them a higher rating points than this. I'm sorry Yohan but I'm just trying to be objective and hopefully on your next drama project, I can see your improvement. A Love So Beautiful Korean Remake is cute and sweet but not really memorable.
