Having lived in the same orphanage as children, Takumi Tsuzuki and Fumino Serizawa grew up together and remain fast friends. Now living and working at a bakery, Takumi does his best to prevent catastrophe, particularly when the clumsy Otome is in the kitchen! He attends school with Fumino and is still the only person capable of reading through her baffling habit of hiding her emotions by saying exactly the opposite to what she means. However, the arrival on the scene of enigmatic catgirl Nozomi may force Fumino to be more honest with her feelings than she is used to - or perhaps even able to. This, along with a host of crazy friends and associates such as the stuck-up Chise and the otaku Ieyasu, ensures that there is rarely a dull moment in their lives!
Have a problem? Talk to Otogi Bank, a student aid group that helps people get what they need – for a hefty price. Led by Liszt Kiriki and staffed by tsundere Ryouko, inventor Majolica, jealous Otohime, flirtatious Tarou, serious Alice, nervous Ryoushi and maid Otsuu, Otogi Bank assists with everything from helping break into a rival school to convincing an upperclassman to not quit a sports team. Can Otogi Bank manage to make all their clients happy, and most importantly, will Ryoushi ever manage to win Ryouko’s heart?
Self-professed lover of all things small and cute, Souta Takanashi finds himself dragooned into working at the Wagnaria family restaurant by the diminutive and vivacious Poplar Taneshima. Though the pay is reasonable and the clientele polite, the high school student is often at his wits' end when dealing with the quirky staff. If the indifferent and street-tough manager, katana-carrying floor chief, and terminally weak Poplar weren't enough, Souta frequently fears for his life, as every encounter with the violently androphobic Inami ends in injury. How long can he survive before the combined stress and harm do him in?
Greatly similar, what they have in common is the ability to make you laugh, a workplace setting with chefs, giving a "sudden appearance" female character a job and home at the place of working, a weird sister(s) to the male protagonist, a traveling boss who randomly comes and leaves the store/restaurant, and a petite high school girl who has a complex about her height. The amount of romance is more or less equal in Working!! and the harem Mayoi Neko Overrun!.
