Updated
The final-season threat
Season 3, the final chapter of Sweet Home, pushes deeper into the origins of the monsters and the backstories of its survivors. New and more dangerous creatures emerge, including human-like beings hatching from cocoons, and the line between human, monster and neohuman becomes the story's central battleground. Cha Hyun-su, still wrestling with his own monstrous transformation abilities, sits at the heart of the conflict as both shield and key. Lee Eun-hyuk returns as a neohuman and allies with Hyun-su, while government and scientific factions keep scrambling to understand and reverse the outbreak. The stage is set for a decisive war.
Defeating Nam Sang-won
The principal antagonist is Nam Sang-won, whose power lets him leap between bodies, making him extraordinarily hard to kill. The climactic confrontation unfolds at the stadium. Sang-won is finally stopped from within: Pyeon Sang-wook, the original owner of the body Sang-won has been wearing, claws back control for a few crucial seconds and hurls himself into fire, killing Sang-won permanently. That self-sacrifice ends the threat that drove the season and breaks the cycle of body-jumping that had made the villain nearly unstoppable, clearing the path for the survivors to rebuild.
Hyun-su's cure and the cost
Cha Hyun-su regains control of his own body and survives the finale. Crucially, he discovers the ability to turn monsters back into humans, transforming himself from a feared anomaly into the instrument of humanity's recovery and a builder of the new world. The victory carries loss: Seo Yi-kyung is depicted dying in Hyun-su's arms after being wounded in the final confrontation. During the battle, both Lee Eun-hyuk and Lee Eun-yu transform into neohumans, and the story signals they will be given time to gradually recover their personalities and memories through the love and support of those around them.
The rooftop and a new era
The series ends on a deliberately hopeful note as humans and neohumans find common ground and begin rebuilding civilisation together. The closing scene returns to the roof of Green Home, where the surviving leads appear dressed in clothing and styling that echo their Season 1 looks, a visual signal that life is edging back toward normal. They watch Eun-yu walk along the rooftop edge listening to music, smiling at the sign that her human feelings may still survive inside her neohuman form. Hyun-su frames this rebuilt world as their sweet home, closing the trilogy on reunion and renewal.
