The only one I haven't seen is "Taipei Exchanges". OMG I agree Gong Yoo's acting in "The Crucible" was superb, definitely pulls at your feels. I'm just sad it was based on true events, it's horrible what some people do. I loved "I'm a Cyborg But that's okay" so weird and cute <3.
I don't know why I keep putting this drama off to the side, even with my friends urging me to watch. But your beginners guide is calling me from the darkness and towards this drama
I loved Gokusen! I actually saw the anime first, and loved it, so when I heard there was a live action version I so had to watch it. I always found myself saying, "How cool would it be if Yankumi was my teacher!" ...but I haven't watched the other two dramas mentioned yet
