This is one my favorite web dramas, it's very rewatchable because of the length of the series and afterwards you can watch the 2nd season. The characters really develop and it covers a lot of topics that high school students struggle with. Also my FAVORITE ost ever by Seventeen. The cast are also pretty good actors and include special guests such as some of the NCT members. I've watch multiple Playlist Global series' and this is definitely my favorite one. It doesn't include mature content so it's good for ages 11 or 12+. Highly suggest you watch.
