Just need to win once.

Overview

A former volleyball star, Woo-jin has been struggling to keep his children's volleyball school that's about to go out of business. Left without much choice, he agrees to coach a women's volleyball team that is the unquestioned worst in the league with only second rate players and an eccentric club owner. According to Woo-jin's contract, all he needs to do is win just 'one' game.
