Drama similar to Age of Youth

Hi, I'm looking for dramas like Age of Youth 1 & 2 since those are my top favourites of all time. It doesn't need to be coming of age or romance genre, it just has to have those kind of nostalgic vibes and a little bit of mystery along with the slice of life plot that AoY has. It just needs to have this special something that makes drama a piece of art. I'd like to be moved after watching this. I also prefer well-developed and believable characters. Thanks in advance.
