POST POST SCRIPT: It's been a few months since I last watched this and I've cooled down a bit. I still really like this, mainly because of the chemistry. There is so much chemistry-
POST SCRIPT THAT I SHOVED TO THE BEGGINING OF THIS REVIEW:
The drama is a drama meaning that it does have misunderstandings between characters, but they always handle them quickly (like think one episode or at most two) and maturely. Characters don't hurt those that they love during hard times, they rely on each other. Most of the characters also respect each others privacy.
The parents are bishes.
The end :)

STORY:
Are you looking for a sweet romance where the leads only have eyes for each other? Want chemistry? Want tons of cute moments? Want no crazy drama? Want the leads to have most of the screen time? No super crazy and stupid misunderstandings or break up scenes? Want second leads (cuz these are unavoidable in dramas) that don't really matter? Want reasonable characters? Want heartwarming family moments? Then this drama is for you!
I don't typically watch romances, I like detective, mystery, serial killing, etc. dramas. But this one was just so simple and lovable. My heart beat so fast I thought it would burst every time the leads looked at each other.

ACTING:
If you didn't tell me that these people were actors, I would have thought that they really did truly love each other. The acting is perfect down to the very micromovements of the eyes and lips. The dubbing (which can't be avoided in c-drama) wasn't the best - but surprisingly, the acting was so good that it made up for the voice over completely!

MUSIC:
The music is perfect. It captures the beauty of whimsical first love perfectly. My heart flutters every time at their song choice. The music isn't overly loud or soft, it plays just at the right spot.
The people who produced this drama are masters at playing around with the audience's emotions with different song choices. Also, the piano music that was chosen was amazing! Yes, I get it, the actors all used body doubles... but does that really matter? Its not like they have to learn a whole new skill that should take years just for a drama.

REWATCH VALUE:
I would watch this tens, hundred, thousands of times over and over again if I could (but I don't think my life will be that long LOL).

OVERALL:
Great cast, great story, great script, great message, great feels. The beginning and ending were perfect. The drama talks to its audience quiet literally, they have these sort of "interviews" at the end where different characters talk to viewers about their feelings and its just so amazing all the way through.
The only thing I would change about this is the second leads. The main characters only had eyes for each other and although the second leads were great at acting, it would have been better to not include them. But... you can never ever ever escape second leads in drama world so-
Just watch it. If you don't like it, leave it. If you like it, you've been blessed. MWAH.
