For years, Shoko has been suffering from a sexless marriage with her husband. One day, while collecting laundry from the balcony, she catches a man stealing her underwear. Startled, she confronts him and demands to know why he stole her lingerie. The thief apologizes, admitting, "You're so beautiful, I just couldn't help myself." Hearing this, Shoko provocatively replies, "If you're a panty thief, then why don't you have some fun with me instead?" From that moment on, their relationship takes an unexpected and passionate turn.
