Honestly I've never written a review but I thought I should write one for this drama.
I first watched the korean version before I watched the original, but so far I've rewatched both of them more than two times. The korean version lacked the depth in characters and in story-telling, and overall I feel like the plot was just cut down. You can barely see the development in the relationship between the ML and the FL, their moments together literally go by so fast. Where as in the c-drama, you can see their feelings grow and change.

Moreover the actor for the FL just looks older than the character should. No matter how they tried to make her appear younger, whether that was through her short hair or making her behaviour so-child like and immature, I felt like the actress didn't really connect with the role and she wasn't really able to bring out her character until the end of the show. (no shade to the actress though shes gorgeous but its just a case of bad casting lols)

And the thing that bothered me the most was how she would forgive the ML so easily. When he told her she was a loser, or when he was caught with Heeji. He would never directly apologize. Like how does playing the piano and telling her 'dont go' when she's thinking of transferring equivalent to an apology? LMAO like okay he could be bad with words and displaying what he feels but this literally makes no sense. You get a sense of his true feelings and some of the reasons behind his actions in the last episode but thats practically it. Overall I feel like this could've been better but its cute for what it is.
