Doukyo Suru Neneki

Yuuji Fujiwara has endured a lifetime of relentless misfortune. From being wrongly blamed for breaking a vase as a child to losing his job over a colleague's error, luck has never been on his side. Even at his part-time convenience store job, a younger coworker named Takamiya routinely shifts the blame for other people's mistakes onto him. Returning home one evening in a state of deep despair, Yuuji is unexpectedly greeted by a mysterious girl. As he stands bewildered, she reveals her true nature: she is actually a sentient slime creature that has secretly shared his living space for the past three months. Capable of speaking human language and altering her form at will, this unusual entity harbors a profound romantic affection for Yuuji. He, however, is entirely unenthusiastic about receiving such devotion from a gelatinous being. Determined to capture his attention and win him over, the creature takes drastic measures. She reshapes herself into the exact likeness of Takamiya, his frustrating coworker from the convenience store, and uses this familiar appearance to seduce him, further complicating Yuuji’s already chaotic life.
