I first held off the drama for a few months even though I knew it was one of the most popular Kdramas of all time. But I decided to watch it and it was amazing. I regretted not watching earlier. The acting and the music were my favorite parts. Everything in the drama was well written and directed. The bromance was so good too. And most of the events made sense and I was able to understand why they occurred and how. I watched this 2 times. Once myself and once with my mom. I enjoyed it both times and got excited and hyped up. My mom doesn't know Korean (I only know a little tiny bit) and we were watching with Japanese subs cause it's my Mom's first language but my mom had a little hard time understanding what's happening and I had to explain it to her. But anyway, I recommend you watch this drama.
