Chôhatsu waitress: Omotenashi cafe

Fumiko and Chitose, the second and third sisters of three sisters, work as waitresses at a coffee shop. With her boyfriend's birthday approaching, Fumiko can't concentrate on her work, imagining that Tsutsuji, the eldest sister with bad habits with men, will seduce him. Suddenly, a man with a knife and a modified gun bursts into the shop.
