Acting:
I loved all the characters, both the leads and support, since they complemented the story well and everyone portrayed their character perfectly to the extent you get carried away with their emotions while watching the drama.

The music:
OST ... Absolutely beautiful, perfect timing, and giving an extra emotion to the scene shown. And as an Army myself Christmas tree was just the perfect addition to this drama, maybe I'm a little biased here?.

The story:
The story depicts various shades of love throughout the episodes, whether it is the first love as high school students, more mature love once they grow older, when there is one sided love, the love between friends and the love of family, and the love for oneself.

Through the documentary these different tones of love can easily be seen and identified, however as they say, there is a reason why roses have thorns, because holding something so truly beautiful as love comes also with sacrifices and sometimes heartaches too.

Overall:
I highly recommend this drama. You're lucky to binge watch it if you like. I had to wait for a whole week to continue the story as I have watched it as it was airing.
