The tvN romance thriller Siren’s Kiss wrapped up its 12-episode run on April 7, 2026, leaving viewers with a shocking reveal about the character everyone trusted the most. The drama starring Park Min-young and Wi Ha-joon kept audiences guessing until the very end about who was really behind the deaths surrounding Han Seol-ah.
The finale pulled back the curtain on Do Eun-hyuk (played by Han Joon-woo), Seol-ah’s closest friend and most trusted person. His confession changed everything about how viewers see the entire story.
The Final Confession That Destroyed Everything
After a tense confrontation where Eun-hyuk held Cha Woo-seok at gunpoint, the truth finally came out. Eun-hyuk admitted to killing every man who ever loved Seol-ah. He explained his twisted reasoning with complete confidence, believing he was protecting her from people who didn’t truly care for her.
Eun-hyuk described each victim’s flaws. Seung-jae was not loyal enough. Su-ho acted obsessive and toxic. Seol-ah’s therapist boyfriend took advantage of her vulnerable state. In Eun-hyuk’s broken mind, he was the only person who truly loved and protected Seol-ah.
What made the scene so painful was that Seol-ah heard everything. She arrived at the location and listened as her trusted friend explained why he murdered the men she cared about.
The Horrifying Truth About Seol-ah’s Parents
The finale dropped an even darker revelation. Eun-hyuk confessed that years ago, when Seol-ah’s parents attempted suicide, he was the one who started the fire that killed them. He found Seol-ah unconscious and her parents already collapsed. Instead of helping everyone, he set the fire and saved only Seol-ah.
His reason made the crime even worse. Eun-hyuk knew that Seol-ah would receive her parents’ insurance money. Kim Sun-ae witnessed the fire and used this secret to control Eun-hyuk as her pawn for years.
“Seol-ah’s final words to Eun-hyuk were cold. She told him never to call her name again.” – Episode 12 Recap
Eun-hyuk also admitted to killing Chairwoman Sun-ae and Yun-ji because both women threatened Seol-ah’s safety. Yun-ji knew about Eun-hyuk killing Seung-jae, so he had to silence her permanently.
Seol-ah and Woo-seok’s Painful Goodbye to Eun-hyuk
After learning the full truth, Seol-ah could barely process what her trusted friend had done. The man she considered family turned out to be the monster behind all her suffering. She told Eun-hyuk never to speak her name again and walked away from him forever.
Eun-hyuk initially refused to confess at the police station. But when he learned that Seol-ah was ready to take the blame and get arrested for everything, he changed his mind. He could not let the woman he loved go to prison. During interrogation, he admitted to all the killings and insisted Seol-ah had no part in any of it.
With nothing left and no one who would ever forgive him, Eun-hyuk took his own life. His death brought his tragic story to a close, though it offered little comfort to the people he hurt.
Seol-ah and Woo-seok Finally Find Peace
The finale did not leave viewers completely devastated. After everything came out, Seol-ah slowly began to heal. Woo-seok stayed by her side during her recovery in the hospital. He promised to be both family and friend to her, asking if they could finally start a real relationship.
This time, free from secrets and fear, Seol-ah agreed. The two shared a kiss that marked a new beginning for both of them.
“Just as Han Seol Ah and Cha Woo Seok saved each other, I hope the drama can provide some comfort to anyone carrying their own pain.” – Park Min-young
Years later, the show showed them building a peaceful life together. They started organizing camps to help children cope with trauma. Seol-ah left the Royal Auction behind and chose a quieter, more meaningful path away from the darkness that haunted her for so long.
Ratings and Viewer Response to the Finale
The final episode recorded a nationwide average rating of 4.5%, peaking at 5.4%. In the metropolitan area, it averaged 4.3% with a peak of 5.3%. The show secured the top spot in its time slot across cable and general programming channels.
Siren’s Kiss also ranked first among viewers aged 20 to 49, tvN’s target demographic. The drama stayed in the top 10 for TV drama buzz for six straight weeks.
Viewers praised the cast performances. Park Min-young took on her first thriller role and delivered a layered performance as the haunted Han Seol-ah. Kim Jung-hyun played the obsessive Baek Joon-beom with intense energy. Han Joon-woo completed the twist-filled role of Do Eun-hyuk, making viewers truly shocked when his character’s dark side came to light.
One viewer comment summed up the reaction: “Finally a drama that matches his energy. This man is about to eat and leave no crumbs.”
