First of all, I'd like to make it clear that I enjoyed watching this k-drama, but that doesn't mean that I enjoyed everything about it, obviously. Even though I think this drama was good, It does not show us anything new, mostly because it's surrounded by all these clichés.
Secondly, I gotta say that as someone who has seen the Chinese/original version of this drama, I did prefer that version instead of the Korean version for several reasons, but still, this drama was really good, and it was still adorable.
One of the reasons (and probably the main reason) that makes me prefer the original version is that the Korean version removed a lot of details from the story which is also something noticeable just by seeing the duration of each episode (about 25 mins). In addition to this, I noticed that there's a difference in the "personality" of the male lead of each version. In the original version, the male lead is actually really cold and you can tell that, but in the Korean version, Heon didn't come across as a cold person, but more of a sweetheart and nice person who was kina of an introvert or something like that.
In spite of this, this is still worth watching especially if you're into the cute, lovely, sweet types of dramas.

When you watch this drama tell me what you think, I'd love to know other people's opinions about this drama. And, also, if you also watched the original version, please tell me which one is your fave!
