Tanaka-san is a plain office lady in her 40s with no friends or boyfriend with a true identity as a super sexy belly dancer. Her colleague, Akari, learns Tanaka's true identity and becomes inspired.
Akari attends a belly-dancing class, but she has a long way to go before she can dance like Tanaka. Shono throws insensitive words at Tanaka, angering Akari. Under Tanaka's influence, Akari and Shono's values slowly begin to change.
Tanaka-san is depressed because she can't dance until she heals her frozen shoulder. Shono mistakenly believes Tanaka has feelings for him and goes to see her. Akari reunites with Shingo and reveals her true feelings.
Tanaka and Akari become angry with Shono. Shono sends an apology through email, but is depressed when Tanaka doesn't reply and decides to head to Sabalan.
Tanaka is confused by the appearance of Aiko-sensei, a legendary belly dancer. She both admires and feels inferior to her. There are also rumors of a past relationship between Aiko and Miyoshi, the owner of Sabalan- and Tanaka's crush.
Shingo and Konishi bump into each other in front of an apartment building, causing Akari to mildly panic. Shono invites Tanaka-san to an "Oriental Dinner Show," marking her first ever date.
Tanaka-san is shocked to hear that Shono had a matchmaking meeting. She throws herself into belly dancing, but receives an unexpected invitation from Miyoshi.
Tanaka is unable to accept Miyoshi's kiss and can't understand her own feelings. Unable to regain her sense of self, Tanaka is banned from dance lessons. Akari takes a serious look at makeup, and Konishi thinks about their future together.
