i enjoyed watching a-teen quite alot. the story is light-hearted and cute to watch tho it also contains some serious topics. the first season is more about the friendship among the friend group, which why i prefer this season over the second one. their friendship is just goals and seeing them hanging out is really fun but the romance which develops over time is adorable to watch as well. every character of them has their own charms and their own problems at home, which makes you relate to them (or i guess in my case at least). especially do hana, who is more in focus than the rest of the group in s1, is really a great character and you'll probably start liking her too because of her straightforwardness, and she is just cool haha ngl.

overall i can truly recommend you this webdrama if you like a highschool slice of life which includes the romance and friendship aspects as well. i'll probably rewatch it some time because it was just very enjoyable to watch, every single episode of it! :)
