“When we were kids, I used to take care of him every day… But now..."

Ja-hyeon has ended up as nothing more than a shuttle(errand boy) for his childhood friend, Kang-bok.

At school, he gets beaten up and has his money taken, and now he even has to clean Kang-bok’s kendo dojo every morning.

“I can’t take it anymore!! If only I could land just one hit…!”

Ja-hyeon challenges Kang-bok, who’s a skilled kendo athlete, to a match.

The result is disastrous…

"Wait, why haven’t I been hit even once?"
