My Girlfriend is a Parasitic Alien! - Volume 4. My Girlfriend is a Parasitic Alien!, #4

Yan Shen thought he finally had justice. After twenty years of living in the frozen silence of his parents' murder, he had put the architect of their deaths, Lin Hao, behind bars. But in the city of Jinghai, the law is often a suggestion. A procedural error and a high-priced legal team have set the monster free, and this time, he isn't just coming for the Yan Corporation-he's coming for the girl in the shadows.
Su Ying is recovering, her energy reserves low, but her resolve is absolute. As she navigates the complexities of "being human"-from making extra-cinnamon lattes to organizing supply closets by color-a new, more clinical terror emerges. Lin Hao has formed a deadly alliance with Yan Li, Yan Shen's estranged uncle and a fanatic scientist who has spent forty years hunting the frequency Su Ying emits.
Armed with the Resonance Core-a weapon forged from the fragments of Su Ying's own crashed ship-Yan Li intends to sever the shadow-bond once and for all, viewing Su Ying as nothing more than a biological specimen to be dissected. As Lin Hao launches Lotus Capital to steal Yan Shen's empire piece by piece, and the Ghost Squad closes in with alien-frequency scanners, the stakes shift from corporate survival to cosmic existence.
In a finale marked by a high-speed highway reckoning and a daughter's heartbreaking betrayal, Yan Shen must decide if he is human enough to love a woman who is fading into white static. The Road ends here. The Glacier must melt, or the Shadow will dissolve.
