My first foreign drama, so naturally this is biased. I have rewatched this many times. I think this one is at the top not because of the story, but the extreme attention to detail. These actors actually act like they are in high school, and the supporting cast is amazing, making it perfect. I found it to be very entertaining, laugh out loud funny, and moving. I especially enjoyed the interactions between Ariel and Joe, who had great on screen dating. I liked how smart Zhi Shu was but how utterly awkward he was in relationships, but because of his beauty, he hides behind a cool and distant demeanor. I think he likes Ariel because of her fearlessness. I do think that this show is interesting in that we have a female stalker, essentially, but because she is a woman no one is bothered by it//were it reversed everyone would be like oh my god stalker guy!
