Walking on Thin Ice Episode 4 Recap: Eun-soo’s Risky Deal Turns into Chaos

In Walking on Thin Ice Episode 4, Kang Eun-soo (Lee Young-ae) made another dangerous move. This time, her bold decision nearly cost her everything. The drama continued to mix crime, trust, and survival in a tense story that kept viewers curious about what would happen next.

Eun-soo’s story took a darker turn. She tried to make a deal with Lee Kyung (Kim Young-kwang) again. She promised to earn 200 million won and give him the rest of the drugs. Her goal was simple—save her husband and pay off the debt.

Lee Kyung didn’t agree easily. He gave her only two weeks to bring in 100 million won. If she cheated again, he said he would show a video of their contract to her daughter, Soo-ah (Kim Si-a). The threat raised the tension between them.

They didn’t trust each other. But they had no choice. They joined hands again to sell drugs online. The money was less than expected. Time was running out.

When all options were gone, Eun-soo decided to meet a buyer face-to-face. She believed it would be faster. But this decision brought a huge problem.

The buyer turned out to be a trap. Eun-soo almost lost both her drugs and the money. She snapped. She threw a brick, & she chased the man on a scooter. The scene felt raw and real, showing a desperate woman fighting for her last chance.

At that moment, Lee Kyung arrived and pulled her out of danger. Their argument after that felt sharp and emotional. He scolded her for taking risks, but her face showed something else—relief and pain.

Danger, Secrets, and New Suspicions

Their secret deal started to leak out. Mi-yeon (Jo Yeon-hee) saw Eun-soo getting out of Lee Kyung’s car and grew suspicious. Even Soo-ah, her daughter, found dirt on Eun-soo’s socks and began to question her mother’s actions. The story slowly showed how hard it is to hide a lie in a small family.

At the same time, Detective Jang Tae-gu (Park Yong-woo) was closing in. He followed the missing James’s trail and began connecting the dots. By the end of the episode, he showed up at Eun-soo’s home with a serious look, hinting that he had finally found something.

The tension reached a peak. Every character looked trapped in their own mess—Eun-soo with guilt, Lee Kyung with his double life, and Tae-gu with his determination.

Actor Park Yong-woo stood out this week. His portrayal of Jang Tae-gu felt calm yet intense. His sharp eyes, quiet tone, and slow movements gave the detective a natural power. When he told a suspect, “Do you want my attention for the rest of your life?”, his cold voice left a deep mark.

Tae-gu’s scenes were packed with detail. He checked CCTV footage. He followed small clues, & he walked into the subway station where James had disappeared.

His face stayed firm, his instincts sharp. And when he appeared in front of Soo-ah’s house with a faint smirk, viewers could feel that something serious was about to unfold.

A Tight Story with Strong Performances

Episode 4 focused on three main threads—Eun-soo’s survival, Lee Kyung’s hidden side, and Tae-gu’s growing suspicion. Each story added weight to the next.

Lee Young-ae gave Eun-soo a strong yet fragile look. Her eyes told the story of a mother who had seen too much but couldn’t give up. Her quiet desperation made the story believable.

Kim Young-kwang played Lee Kyung with smart balance. He looked calm but dangerous. His tone shifted from soft to cold in seconds. His character worked both as a partner and a threat. The dual nature kept viewers hooked.

Their chemistry felt sharp, not romantic. It was built on mistrust, money, and survival. That made it more real.

The drama doesn’t slow down. Every scene feels necessary. The camera captures the gray tone of the city, matching the characters’ inner struggles. Nothing feels glamorous. Everything feels raw.

Lee Kyung’s True Face Still a Mystery

Lee Kyung remains one of the most interesting figures in the show. He acts calm, but his anger comes fast. He helps Eun-soo one moment and threatens her the next. His question—“Do you know how I survived in this world?”—still echoes.

This dual side makes viewers wonder what he’s hiding. His scenes with the Phantom drug gang hinted that he knows more than he admits. The tension in his eyes when he learns that Eun-soo switched the drugs said everything.

That moment, mixed with frustration and disbelief, made the character real. He wasn’t just cold. He was human—angry, tired, and trapped by his own choices.

Episode 4 ended with all characters facing their limits. Eun-soo’s secret is about to explode. Lee Kyung’s control is breaking. Tae-gu’s investigation is closing in.

The next episode looks set to show who falls first.
