Yoo Yeon-seok Sings Final OST for 'When the Phone Rings' – Even Wrote the Lyrics for 'SaJoo Couple'

As MBC’s Friday-Saturday drama 'When the Phone Rings' nears its finale, actor Yoo Yeon-seok has revealed a surprise: he will sing the drama's final OST.

The track, titled "Say My Name," will be released on January 4 at 6 PM KST through major music platforms. Yoo Yeon-seok not only lends his voice to the song but also contributes to the lyrics, infusing the track with a personal touch. Reflecting his character Baek Sa-eon's deep and tender love for Hong Hee-joo(Played by Chae Soo-bin), the heartfelt song highlights the emotions at the core of the story. Yoo further emphasized "sunset" as a central motif, beautifully capturing the unique sentiments of the drama’s beloved 'Sa-Joo couple.'

The title "Say My Name" holds profound symbolism, encapsulating the drama’s central theme. This resonates deeply with the revelation that Baek Sa-eon has been living under a false identity. A pivotal question remains: will Baek Sa-eon's true identity and real name finally come to light? And, perhaps more importantly, will Hee-joo call him by his real name?

The drama’s previous OST has already gained global recognition. The first OST, "See The Light" by BTOB’s Lim Hyunsik, climbed to 10th place on the Billboard World Digital Song Sales chart, highlighting the series' growing popularity alongside its music. With Yoo Yeon-seok's upcoming release, anticipation is higher than ever.

'When the Phone Rings' concludes on January 4 with its 12th and final episode. Starring Yoo Yeon-seok and Chae Soo-bin, this secretive romantic thriller tells the story of a couple in their third year of a loveless, arranged marriage. Initially bound by blackmail and deception, the two gradually uncover each other’s hidden truths and emotions. With its blend of suspense and romance, the series has captivated audiences both domestically and internationally, cementing its finale as a must-watch event.

A key mystery in the remaining episodes is whether Chae Soo-bin’s character, who has gone missing, will safely return to Yoo Yeon-seok’s side. In the previous episode’s gripping climax, Hee-joo, held captive, made a bold and dangerous decision to protect Sa-eon from the kidnapper. As the story nears its end, all eyes are on the fate of these two star-crossed characters.
