Hello! Yes, most k-drama fans who've been around a few years probably have. It was hugely popular when it came out. And even though the story wasn't as well plotted as we had hoped, a lot of people loved it because of the chemistry of the leads and the excellent supporting cast.
Yup. When it came out, it was widely watched, more so because of how popular the leads were at that exact point in time. While it was basically the epitome of certain tropes, it was fun. I still listen to the OST often.
