Kousuke has an unusual ability: he can see the red string of fate that connects soulmates. Much to his misfortune, he falls in love with Yuka, whose string of fate clearly doesn't lead back to him. He hides his feelings for her, until the day when a fortune teller says to Yuka that her destined lover is nearby—and she thinks it's Kousuke! If this is Kousuke's chance to pursue the woman he loves, will he have to fight destiny to be with her? (Source: Seven Seas Entertainment)
