Born in an elite family, Nao happens to have some leisure time only at night. Her only desire is to experience true love just once before her wedding day, which has been decided since birth. Nao visits the bar Labyrinth every day in the hope to meet the man of her dreams but never does. Ichikawa and Misao also happen to show up at the same bar separately. But to their unfortunate luck, as if there were never to see each other again, they never come face-to-face. Just then, Nao, who believes that Deno is the man of her dreams, spends the night with him, keeping her secret unrevealed.
