Yuji Fujiwara has been plagued by misfortune throughout his life. His troubles began in childhood when he found himself falsely accused of breaking a vase he had never even touched. This streak of bad luck followed him into the workplace, where he faced his coworker’s enrage committed by his colleague. To make matters worse, Takamiya, a young woman at the store where he worked part-time, seemed to delight in blaming him for the errors of others.
Returning home each day, battered by the weight of these constant challenges, Yuji’s world took a surreal turn one evening. It was started when he encountered a mysterious girl, a being that defied the boundaries of normality three months ago. As it turned out, this girl was no ordinary human; she was a shape-shifting slime, capable of taking on various forms. They have been living together in a past three months. Desperate to win Yuji’s affection and attention, the shape-shifting slime hatched a daring plan. She transformed herself into Takamiya’s appearance, and seducing him like she always do.
