Yoo Yeon Seok and Chae Soo Bin's married life takes a dramatic turn in When the Phone Rings

When the Phone Rings promises nerve-wracking suspense and thrill.

When the Phone Rings centers around a couple — Baek Sa Eon (Yoo Yeon Seok) and Hong Hui Ju (Chae Soo Bin) — in their third year of arranged marriage. Despite being together for three years, the two have neither communicated with each other nor shared a meal. They would have continued living as usual, until their lives were turned upside down by a threatening phone call. 

With the premiere just two weeks away, the K-drama dropped the third teaser, offering a glimpse into the characters' lives.

The teaser begins with Baek Sa Eon warning Hong Hong Hui Ju not to come publicly as his wife. He also coldly pushes her away, saying, "Don't bring emotions between you and me," sparking curiosity about why he does not want Hong Hui Ju to come in public as his wife.

They would have continued to live as a show window couple had it not been for a phone call Sa Eon receives threatening Hui Ju has been kidnapped.

After the threatening call, Sa Eon begins to monitor Hui Ju's every move. As he does that, the two start to get to know each other deeply through conversations in sign language. However, the blackmailer who continues to threaten Sa Eon and Hui Ju warns, "Once I start, I see it through to the end," refusing to back down easily. This raises suspense and curiosity about the blackmailer's identity.

In a surprising twist, Hui Ju, who suffers from mutism due to an accident in her childhood, shouts at the blackmailer. Whereas Sa Eon doesn't seem to even waver despite his wife's kidnapping, highlighting the empty relationship the couple share.When the Phone Rings will premiere on November 22. The K-drama will be available to stream on Netflix. Watch the teaser here.
