I forgot to mention one of my favorites.
"lovely love lie". The best way to describe this show is an adorable puppy dog that pouts a bit. Some young angsty romance, but the stakes are never too high so it's very lighthearted and cute most of the way... plus there are lots of nice pop songs and attractive idols. similar vibe to kim bok joo.
great if you want something cute and fun. https://www.youtube.com/watch?v=zgwufvkOd8s
