Once known as the "Goddess of Victory," former national volleyball player Eun-gil is now a "national traitor" playing for a living. The only person who remains a die-hard fan by her side is Mina.
Trying to save Mina from an unwanted arranged marriage, Eun-gil is reunited with her team owner, Ha-hyun, a man she had hoped to never see again. To make matters more complicated, she discovers that Mina is actually Ha-hyun's younger sister.
Ha-hyun then makes her a shocking offer:
"If you have to stay with Mina, you'll have to marry me first."
A marriage stand-in?! What on earth is he talking about?!
