Muscle Girl - I adore Hongki, both as an actor and as a singer, but it was such a waste for his skills, the story was nothing special for me.
Buzzer Beat - it was so long ago and I don't remember the details, but I was really looking forward to Yamapi's another drama, and I actually liked it for a while, but in the end I couldn't stand it so badly that I dropped it 2 episodes before the end. The main characters' indecisiveness was just too annoying, and I couldn't stand his previous girlfriend and his attitude toward her. Still it has the only real kiss I've seen in a Japanese drama, so it deserves some credit for that.
Love contract - It just lost the story line somewhere, it's a drama where there's nothing going on. And I don't like Ariel Lin. Even Mike He was boring in this.
