The top four fighters in the preliminary have been decided. With her semifinal match against Daewi drawing near, Mira is suddenly approached by Oh Seongjin, a martial artist and successful businessman, with a marriage proposal. She agrees to marry him in exchange for his promise to restore her family’s dojo and spread the Moon Light Sword Style around the world, but marrying him means she must withdraw from the tournament… and Mori and Daewi are not okay with this.
