Struggling to keep up with rent while balancing her studies and a broken heart after an accident sidelined her boyfriend from work—Tsubaki finds herself in desperate straits. The sympathetic landlord quickly capitalizes on her vulnerable position and their shared financial stress. Rather than simply offering a job as a maid to cover the overdue apartment fees and utility bills for Tsubaki and her partner's cramped lodging,
he insists she must also serve as his personal lover. Reluctantly at first but driven by necessity (and perhaps a little temptation), Tsubaki dives into the role of housekeeper-cum-mistress. She excels at every domestic task while simultaneously satisfying the landlord's desires. Their arrangement proves effective; Tsubaki diligently works until her boyfriend secures new employment and manages to pay off the mounting debt owed to him.
Though finally granted freedom from the contractual obligation, the intense pleasure derived from the landlord’s attentions leaves an indelible mark on Tsubaki’s memory. The experience was far more intoxicating than just paying bills! Now yearning for more intimacy, she proactively seeks out his residence, eager to return to her duties as his devoted 'housemaid,' ready to continue pleasing him whenever he calls upon her.
