This movie is nice and sweet! Although the ending made me cry buckets of tears, it was worth every tear! A must watch for everyone who loves the light romance genre!

I liked how the storyline was clean, simple and straight to the point! Not much conflict, nor unnecessary drama just the way a summer high school movie vibes should feel.

The plot was great from start to middle but towards the end, it felt lacking and a bit rushed. Some of the details weren't given to us, i'm guessing the writer intended that for us to conclude on our own?

The casting was great too! The story out worked well even just by revolving the story around the four characters.
Kim Yoo Jung was perfect for the role, and looking at the two boys, i'm just squealing!

Overall, 20th Century Girl was able to deliver with the setting and made us feel exactly what a high school crush and first love feels like (wanting to know more about the person, stalking, sneaking looks, etc.). 2 hours for a good movie like this is so short I was hoping we get to see them live and enjoy their high school days more!
