Lin Qinghe transmigrates into an interstellar novel as a vicious female supporting character. Right at the start, Major General Lu Li, the original male lead, breaks off their engagement. She happily agrees and walks away with a 50-million breakup settlement, only to be matched with an abandoned beastman who cannot transform into human form. At a shelter, she brings home Ling Shu, a gray cat covered in wounds. Everyone doubts her, but she patiently pieces him back together, one little bit at a time. His tail wraps around her hand, he secretly rubs against her, sleeps in her bed, and waits for her to come home. Ling Shu becomes a hopeless romantic who only has eyes for her. Eventually, the gray cat regains his human form—but before the two can even enjoy their newfound intimacy, the military comes knocking. That useless cat, Ling Shu, turns out to be the empire's supreme ruler, missing for three years. This time, everyone is left dumbfounded.
