I'm having mixed feelings and this 15th felt like a stab in my stomach, dear god, this I can't imagine how painful was to lee Ahn , he basically lost almost everyone who was dear to him, and I was trully in shock about this turn of events, wasnt expecting that Kang Geun Taek would basically set everything but sung mo would be the one using, it makes sense actually, this is so well written, so well developed, props to the writter seriously, and their acting... this drama is insanely good

Btw I noticed that you watched 30 episodes, did you watched it raw or with eng subs?
