The Arum, powerful entities in the book "Obsession" by Jennifer L. Armentrout, lack inherent feelings, contrasting with characters like Dex, who do experience emotions. This difference highlights the disconnect between the cold nature of the Arum and the emotional depth present in other characters, emphasizing a sense of isolation among them.

Dex's situation takes a concerning turn as he grapples with the unpredictability of the Arum’s behavior, which becomes dangerously erratic. This shift into what is described as "offhisfuckingrockerville" suggests a breakdown in the Arum’s composure, creating tension as Dex navigates this volatile dynamic.
