The two actors Park Yoochun and Kim Hyun Joong are fighting fiercely for the number 1 spot. They are both appearing in dramas that air during the same time slot.

According to Nielsen, the audience measurement company, the March 13th broadcast of Park Yoo Chun's SBS "Three Days" recorded a 12.7% viewership, the highest of all other shows during that timeslot. It was 1% higher than last week's broadcast (11.7%), and in just 4 episodes it has beat out all other broadcasts during that time, and is standing at the top of the list at number 1.

In 2nd place was KBS 2TV's "Inspiring Generation" with a viewership of 12.6%. This drama featuring Kim Hyun Joong lost the top spot by just 0.1%.

As you can see, the difference between "Three Days" and "Inspiring Generation" is at a mere 0.1%. Given the margin of error, it's difficult to say it's a clear win. That means the competition is that close.

Interestingly, the number 1 and 2 dramas both feature acting idols. JYJ member and actor Park Yoochun and SS501 member, solo artist, and actor Kim Hyun Joong are battling not with their music but their acting. It's amazing that these two acting idols stand where they are today, especially since they both started out as singers. They will continue to work hard to stand out from other actors and outdo one another for the highest viewership.

Of course, it's hard to compare the two actors by the drama they star in. It also depends on the drama's script, cast, and other actors' acting skills as well. But overall, since these two actors are the lead roles, we can attribute some of the credit to their acting.
