When the Phone Rings

About

"A Chilling Connection That Shatters a Perfect Silence" When the Phone Rings is a high-stakes mystery romance that begins with a single, terrifying phone call. The story revolves around a powerful and elite couple living in a loveless "show window" marriage. Their carefully constructed, icy coexistence is thrown into chaos when a mysterious kidnapper calls, threatening their world. As they are forced to work together to survive the threat, long-buried secrets surface, and an unexpected, simmering tension begins to ignite between them. The drama’s visual style is defined by "luxury mystery"—featuring grand, minimalist interiors, high-end corporate offices, and the atmospheric, rain-soaked streets of Seoul. The locations reflect the emotional distance and hidden desires of the protagonists, contrasting the cold glass of skyscrapers with the intimate, hidden corners of the city where the truth slowly unravels.
