I was late watching this drama, but I had a drama marathon with about 15 episodes, it was worth it. Loved the story, it was different than k-dramas, it gets in more of the emotions. Mystery, a mellow romance,.. I also got the soundtrack. I love listening while watching. It's with my favorite tai-dramas soundtracks. Besides Baren Chen of Bromance, marcus is also is my favorite, I'm going to watch his other drama on Netflix-1989. I hope episode 19 isn't the last episode of Behind your smile. I'll well be disappointed. Some sights says it's up to 24 episodes. Please let it be! Awesome Drama, loved it.
