Honestly? Uh, wow. This one blew me away. Got way more than I expected. It seemed so perverted and light-hearted and funny, but things start getting deep later on in the series. There's good character development for all of the major characters and the relationships are all fantastic. I found myself laughing here, and crying there sometimes as well. The drama is strong!
Story: Due to the premise of highschool girls having their lives overtaken by sex, it was easy for me to mistake this for some kind of gag anime. But there's a lot of thought and detail put into every episode and every interaction. The journey from start to finish gets better and better.
Art: Sometimes the art is cute, sometimes it's intense. But there's never any drops in quality. It maintains a strong quality throughout the entire series.
Sound: The OST is great - whether it's for the funny scenes or the sad or intense ones. The opening and ending themes are quite memorable as well.
Character: If you've read any of my other reviews before, you'll know how much I enjoy the characters. For me, characters are everything. And like I said in the synopsis of my review, the character development in this series is astounding. You essentially have a group of kids who take a laugh and tear-filled journey into becoming respectable young adults.
Enjoyment: I loved this series so much that I couldn't stop watching it once I started. Easily a binge-worthy series from start to finish.
