I am not sure if it really deserves 10 stars or if it is only my enthusiasm, but I didn't have in a long time a TV show that would keep me dreaming about it at night and not being ale to stop it.
I did not have the patience to read all the reviews but i have so many comments that I don't even know where to start.
First, I consider this being such a powerful and emotional lesson for all of us, no matter the age. People should really try hard on learning how to grow up, how to express their feelings, how to laugh even though you are in a bad situation and how to get over that bad situation with dignity and more knowledge about you and about others. From my point of view, this is not only a teenage drama since a lot of people in the world are still not able to do all the mentioned above things.
The TV show also shows you the power of extreme friendship, not only love power to forgive and to care, power to accept who you are and to accept others.
I've seen in a comment that it is sexist because it is the well known subject of strong male character and weak female character, but guess what ? That's the reality in Korea and in other Asian countries, guys. Women have very not even half of the power and benefits of the men. Yeah, if you want to watch a SF drama with a superhero girl, just move over this title. It is not time for K dramas to adapt to the 21st century as some said below, but it's time for Asian cultures to respect women more strongly and to recognize them.
Also, people said that the actors to not look like 18 year old students. Guys, really? If you watch an American TV show with teenagers you will be surprised how the 16 year old girl look like and behave in these days. Korean actors from my point of view, all look like teenagers and they are very beautiful at the same time.
To conclude, even though I have a lot more to say but I think it's better to stop here, don't hesitate to watch this movie, especially if you like romantism.
