### Summary
Confirming reader speculation from the previous cliffhanger, Seo Taeyoon’s physical collapse was the onset of his long-awaited rut, not a medical crisis, and his infant son, Jaeyoon, is safe. The chapter depicts the primal intensity of the event, with Park Jae-in discovering Taeyoon fully consumed by his alpha instincts. Readers noted Taeyoon’s glowing eyes and a feral expression that was simultaneously frightening and exciting. In a significant and unusual display, Taeyoon has built a nest, an act typically associated with omegas, using Jae-in's clothing which he has also covered in his own scent and fluids. The chapter ends on a tense and highly anticipated cliffhanger as Jae-in enters the pheromone-saturated room and the rut-driven Taeyoon turns his attention towards him, reaching for his mate. The scene sets the stage for the couple's permanent biological bonding, leaving readers speculating about explicit "rut sex," knotting, and the potential for a second pregnancy.
