1. Kang Moo Kyul & Wi Mae Ri (Mary Stayed Out All Night) The actors are very likeable in their roles and do a good job portraying their characters; they have such an amazing chemistry! The fact that they stay together through everything is amazing. I really really enjoyed watching their romance evolve.
2. Baek Seung Joo & Oh Ha Ni (Playful Kiss). A lot of people didn't like the way Seung Joo treated Ha Ni, and also felt like Ha Ni was depending too much on Seung Joo... BUT! Seung Jo was much more reserved, and had a hard time showing his feelings, yet he managed to do it! Ha Ni kept waiting for him, because she knew that was she was experiencing was true love. I could relate to both characters really well, but I do understand if you can't really relate to them, you might not get the same emotional attachment to their relationship, like I did.
3. Jung Joon Hyeong & Kim Bok Joo (Weightlifting Fairy Kim Bok Joo). This is a newer kdrama couple, but holy moly their chemistry was amazing. It might have to do with the fact that they're from the same company, and therefore they knew each other before hand, but we can all agree that both of them are amazing actors. I'm always a huge fan of how Lee Sung Kyung acts, because she is never scared of ruining her image! Nam Joo Hyuk is so charming, and when you put these two cute human beings together it's like BAM cuteness overload!
I don't know what to comment on bad & ugly ones, because I don't really focus on them. If I don't feel any chemistry, I'll probably drop the drama, or give it a lower rank.
