넷플릭스 당신이 죽였다

📌 Synopsis

Hee-su has been suffering from severe domestic violence at the hands of her husband, Jin-pyo.

Living inside a cycle of fear that never ends, she sees no way out.

Her friend Eun-su eventually learns the truth and suggests killing Jin-pyo to stop the abuse— but unexpected events begin to unfold, pulling multiple characters into a dark chain of consequences.

📌 Main Characters

Eun-su (played by Jeon So‑nee)

A VIP sales associate at a department store.

Highly responsible and strict about her work.

She has painful childhood memories of pretending not to notice her mother being abused by her father.

When she witnesses a VIP customer suffering domestic violence and later committing suicide, something inside her snaps.

So when her close friend Hee-su becomes a victim too, Eun-su chooses what she believes is the “final solution.” My note: Her relationship with the VIP clients felt unusually close, which made her position inside the store slightly ambiguous.

Still, her loyalty and determination toward her friend were convincing.

Hee-su (played by Lee Yoo‑mi)

A once-promising children’s book writer whose life collapses after marrying Jin-pyo.

She tries multiple times to escape but consistently fails.

Out of desperation, she even considers killing her husband, yet it is Eun-su who ultimately offers to take that burden.

Acting note: I want to look forward to playing a happy role by only playing a role with a story every time. Among her works, the happy role of "Strong Woman Gangnam Soon" came to mind.

Jin-pyo/zang jang(played by Jang Seung‑jo)

A man obsessed with how others perceive him— well-dressed, polite in public, but violently abusive in private.

His duality is the trigger of everything that follows.

Personal thought: Jang Seung-jo is usually cast as a clean-cut, gentle character, so watching him play this role felt unsettling—in a good way.

His performance is strong enough to make viewers uncomfortable.

Jin So Baek (Lee Mo Saeng)

He plays the role of a tall man in this work. He seems to have lived a rough life, but he seems to have a weak mind. He thinks that Eun-soo and Heesoo did it because of what they said, and helps them. It reminded me of a father who takes care of his daughter, who does not listen to what she says until the end.

📌 My Thoughts

This genre is not something I usually enjoy, but I watched it out of curiosity as soon as it was released.

The actual story begins when Jin-pyo’s violence escalates and someone starts to die.

If Jang-pyo’s character had not shifted so dramatically, the narrative wouldn’t have moved forward.

Watching Eun-su and Hee-su attempt to break free only to fail repeatedly was frustrating— and that frustration is exactly what the show intends.

I completely understood Eun-su’s reactions: “Is this really the best option?”

“Do you have to live like this?”

“Why must it come to this?”

Even Jin-sobaek’s (Jin-pyo’s) single remark is enough to push the characters into irreversible decisions.

Jin-pyo’s younger brother also shows how a person can destroy his own life while refusing to admit the truth.

People blinded by obsession often refuse to see what’s right in front of them.

This drama is based on a Japanese original, and I’m curious to check out the source later.

📌 Best Moment


Detective Choi (played by Jo Han‑joon)

Unlike his senior Jin-young, he trusts his instincts rather than hierarchy.

He eventually approaches Hee-su to apologize and extends a genuine hand of help.

His final confrontation scene—removing Jin-young’s hat to expose him—was unexpectedly satisfying.

For me, the standout part was Detective Choi confronting Jin-young with quiet confidence, choosing integrity over loyalty, and finally revealing the truth without hesitation.

The tension and release were perfectly delivered.

📌 Final Verdict

A compact but gripping thriller driven by strong performances and character tension.
