"Triangle" has led the race for the first place in the Monday-Tuesday night drama ratings but this week it lost the lead to "Doctor Stranger." And it lost second place to "Big Man."

"Doctor Stranger" led the ratings with 12.1 percent, while "Triangle, fell from 9.6 percent to third place with 7.5 percent.

What happened? In the latest episodes of "Triangle," both Im Si Wan's and Kim Jaejoong's characters are falling for Baek Jin Hee. They become gambling and romantic rivals without any idea of their relationship. The brothers, although raised in different environments all display the same impulsive behavior that can lead to their undoing.

Meanwhile "Big Man" rose to 9.7 percent and landed in second place.

It feels as if the plot of "Triangle" is slowly leading up to something, a mess of some kind that all three brothers are involved in, but it may be taking too long to get there. The slow dark-themed plot development could not compete with the fast-paced comic book action of "Doctor Stranger" or the well-established plot dynamics of "Big Man."

In "Doctor Stranger," the plot grows more complicated with every episode. Kang So Ra's character is involved in a romance with Park Hae Jin. She meets Lee Jong Suk when he saves a patient she could not help. At first she is furious that he operated on the man without a medical license. She slaps him and when he talks back to her, she slaps him again. It's not the best way to meet.

At the same time his efforts to find his lost love, played by Jin Se Yeon, lead him to the Myeongwoo Hospital where he encounters a doctor that looks just like her. At first he thinks his childhood friend might have escaped North Korea and become a doctor. His quest to uncover the truth will lead him to work at the same hospital.

In "Big Man" Lee Da Hee learned more about the unhappy future of the adopted sibling played by Kang Ji Hwan. Having adopted him in an unsuccessful attempt to harvest his organs, the family of his supposed brother, played by Daniel Choi, now wants to get rid of him. But Lee Da Hee's character learned about the plot early on and can't help but feel sorry for him. Daniel Choi's character initially seemed like a nice guy and well worth saving, but he begins to show his true colors as he worries about losing Lee Da Hee to his supposed brother.

Will subsequent airings spark another upset in the order of the dramas or has their order settled into place? What do you think? Let us know.
