Don’t Worry, Sweet Home Season 3 Fixed Your Biggest Song Kang Hyun-su Complaint
Sweet Home season 3 fixed your biggest complaint about season 2, giving Song Kang’s Hyun-su the storyline he deserved in the K-drama’s final chapter.
How Eun-hyeok Is Alive In Sweet Home Season 3
He Was Thought To Have Died In Season 1
Though Eun-hyeok sacrificed himself for his fellow Green House residents' future, Eun-hyeok’s saving grace was the fact he had been infected with the monsterization virus. One of the benefits of monsterization is accelerated healing, which is likely to have played a part in increasing Eun-hyeok’s chances of survival. As such,Sweet Homeconfirms that Eun-hyeok survived the building’s collapse because he turned into a monster.
ThoughSweet Home 2ended with the cliffhanger of Lee Do-hyun’s return to the series, he does not appear on-screen until episode 3.

It’s unclear as to exactly when Eun-hyeok turned into a monster. However, he is presumed to have turned just as the building was collapsing, as Eun-hyeok began to show major monsterization systems as the building fell through excessive nosebleeding. This would explain his miraculous survival and a regular human would likely not make it in such circumstances. Following this, Eun-hyeok is then presumed to have spent some time as a monster before entering the next phase: cocooning.
Eun-hyeok’s cocooning phase explains his late returntoSweet Home. Much like his prior phase, it is unknown how much time Eun-hyeok spent inside his cocoon. However, it was enough time for him to enter the last stage of the monsterization process. As seen in the final moments of season 2, Eun-hyeok emerges from the cocoon as a neohuman. Though he looks similar to his season 1 character, Eun-hyeok’s appearance inSweet Homeseason 3proves he is now an entirely different person.

Why Eun-hyeok Looks So Different In Sweet Home Season 3
Sweet Home Season 3’s Eun-hyuk Is Not Human
Neohumans may look human, but they are anything but.Neohumans are entirely new beings that have the ability to be reborn after their death, making them almost immortal. Eun-hyeok demonstrates this process in episode 3. He dramatically takes his own life after having been attacked by Sang-won (Lee Jin-uk) at Bamseom but is quickly pulled into a cocoon and reborn again as the same Eun-hyeok as before. Though this process acts as a gateway to immortality for the neohumans, it comes with its own issues.
ThroughoutSweet Home 3, Eun-hyeok carries a family picture with him. This family picture has sentimental value for Eun-hyeok, who was last seen holding this photo just before his death. This implies that Eun-hyuk can remember his past life. However,Eun-hyeok’s status as a neohuman means that he cannot experience any emotions. This takes a toll on his reunion with his younger sister, Eun-yu (Go Min-si), who asks him to use his accelerated learning skills to learn how to use emotions, in the hopes she can regain more of the brother she once had.
Neohumans like Eun-hyeok are proof that monsterization isn’t the end of humanity, but perhaps even a new beginning.
The introduction of the neohumans adds a welcome new twist toSweet Home. These beings add a new dimension to monsterization but they also provide a sense of hope. Up until now, all cures made for the virus had been destroyed or hidden by Dr. Lim (Oh Jung-se), who saw humanity as a sickness rather than something that needed to be cured. Neohumans like Eun-hyeok are proof that monsterization isn’t the end of humanity, but perhaps even a new beginning.

Eun-hyeok and the neohumans believe that the special infectees are disrupting the natural order of the monsterization process and seek out Hyun-su’s help as only a monster-human can defeat someone like Sang-won, who became a half-human half-monster due to the experiments of Dr. Lim.
