/Jungkook before the marathon event/

Jungkook: "Okay Jungkook. Just imagine GD sunbaenim is in front of you, asking you to run faster to catch him up."

Jimin: *comes out of nowhere* "Kookie fighting!!"

Jungkook: "And just imagine Jimin is behind you, asking for a kiss."

And that's how Kookie ran like a cheetah on Idol Star Athletics Championships.
