I'm not exactly sure how to start out a topic of a drama but I have a burning question I really want to ask and hopefully someone can answer it for me.

To start off, here is the information of the drama: http://wiki.d-addicts.com/Tumbling

Starting: Yamamoto Yusuke and Seto Koji.

I just finished this drama and I love it to death. I admit, it sounded it a little fruity when I first started but it did not disappoint. There is a lot of jumping and dancing and tumbling. The actors do all of their own stunts. The humor is subtle but very noticeable (i.e. facial expression, background action, awkward interactions, accidental slaps in the face, etc.).

The general theme is about teamwork, friendship, overcoming obvious physically obstacles and change.
Check it out!




Here's my question:

Click on button to reveal/hide spoiler:

At the end, Kiyama asks Kashiwagi-sensei if it is hard to take the lead. Kashiwagi looks at him for a second, confused. Kiyama tells him, "Nevermind" and backs away awkwardly. What does that mean? I don't get it. Could someone please explain.
