Once hailed as the youngest national representative and the Goddess of Victory, Eun-gil is now branded a national traitor, struggling to survive as a volleyball player. The only one who has stayed by her side is Mina, a die-hard fan. While trying to save Mina from an unwanted arranged marriage, Eun-gil ends up face-to-face with Hahyun, the team owner she never wished to see again. She hadn’t known all this time that Mina was Hahyun’s younger sister. “If you want to stay close to Mina no matter what, then you’ll have to marry me first.” A stand-in marriage?! What on earth is he talking about?!
