Satou Fuuka is an orphan. Her aunt, who was her guardian, absconded in the night, leaving her with no money. Her parents wanted her to go to school, so she was looking for a job to cover her school expenses and rent. She goes to be interviewed for a part-time house helper job but is rejected before she can say anything, because the guy offering the job is the eldest for 4 brothers and it's an all-male household. She pours out her story, so he takes pity on her and offers the job as a live-in position. However, he has one condition: she's supposed to disguise herself so his brothers don't take an interest in her. Her disguise: lots of towels around her body, so she looks fat; makeup so she looks old (39); plus her hair is all loose and she's wearing glasses. (Source: MU)
