This drama is quiet good to begin with. The idea of it may dated but it has such a strong appeal to me because some additional elements. This drama has a strong start and it becomes draggy and clingy from an episode to another. For me, around episode 50 until almost the ending, the drama become draggier and more
clingy. Too much unnecessary things added and potrayed in the drama, making me bored to watch it. Thus, i skip and fastforward the drama when i watch it. Plot holes and inconsistency exist inded. But, it doesn't ruin the story of the drama. What i dislike from this drama is the fact that it emphasized on love story and details a lot more than the whole story. Even the title is Inborn Pair, i expect it doesn't revolves on the leads love story with that much details. Surely, those details can be extinguished from the drama since it won't affect the overall story and the meaning of the drama. 60-65 episodes will be plenty enough for the story.

For the acting, all are good. I'm especially impressed with the little boy (he's so cute tho). Each casts potray the charatcters well even at several moment some characters went overboard.

For the music, i really like the opening. When i listen to it, it just please my ears
