I often watch Kdramas on my commute. This drama is one I recommend you watch in a comfortable place, with easy access to tissues, as it gets quite emotional and will most likely tug hard at your heart strings.

Don't be fooled with the "chaebol cold guy, sympathetic poor girl" synopsis, as this story is so much more than that. Or, should I say - it adds a whole new layer to this kind of plot. You still have the typical characters of controling parent, love rival and so, and although kind of cliché, it adds to the main story revolving around the FL and ML.

Main reason to watch is the performances of the two main leads.
Especially the FL does an exceptional job I think, in portraying and displaying all kinds of emotions; despair, wishfullnes, disbelief, resolutness, love ...
ML is also delivering a strong performance. I like this character's development, and also how he handles it; we can see the changes he goes through in his expressions and body language.

To be honest I don't really remember the soundtrack. It kind of makes sense the music took a backseat in this, but at the same time I have watched other series where the soundtrack still can evoke emotions, so they might have missed an opportunity here as well.

When I had watched around half of the episodes I ended up binging the rest, as I wanted to finish it before my vacation was over.
