Seriously amazing. Outstanding acting. Outstanding cast. I 100% recommend watching this, it's shorter so you can finish it quickly and the plot is so good. I do have to say Rieuls relationship with Ahyi bothers me because it seems like he wants to be with her in a romantic way and she's a minor. Another thing is the plot kind of falls flat at the end because we never really found out what happened to Ildeung, like did he follow in Rieuls footsteps because he started having the symptoms in last episode? It seems like a season 2 should happen and focus around him. Honestly I watched this not knowing it was a musical but I wasn't disappointed. I wish there was a bit more on Ahiyis mom but I get that wasn't the point of the show but it would've made the plot much better. I recommend watching this drama, it definitely will stay in my brain for a long time.
