'21st Century Grand Duchess' Byeon Woo-seok Concludes with OST 'Parallel Lines'

Actor Byeon Woo-seok will sing the final OST for the MBC Fri-Sat drama '21st Century Grand Duchess'. With only two episodes left this weekend, he will conclude the work with a song he performed himself.

Kakao Entertainment announced on the 14th that OST Part.11 'Parallel Lines' will be released through various online music platforms at 6 PM on the 15th. Byeon Woo-seok, who plays the role of Lee An-daegun, adds deeper meaning by singing the track himself. IU, who plays Seong Hee-ju and originally debuted as a singer, did not sing an OST in this work.

'Parallel Lines' is an emotional ballad that captures the love of two people who lived in different times and social statuses. It depicts the fate where two lines, which seemed as though they would never touch, eventually meet at a single point. Built on a structure that opens with a dreamy piano melody and gradually builds emotional tension, Byeon Woo-seok's deep and warm tone is layered on top.

A portion of the song was first revealed during the ending of the 10th episode, spreading quickly among viewers. 'Parallel Lines' played during the scene where Seong Hee-ju, who faced trouble after their contract marriage was revealed to the outside world, and Lee An-daegun reconfirm each other's sincerity, and Lee An-daegun is once again placed in crisis as he is engulfed in flames. Immediately after the broadcast, requests for the official release of the music poured in on SNS and online communities.

Byeon Woo-seok expresses Lee An-daegun's wavering emotions with a restrained tone. He connects the lingering emotions of the drama through his voice, conveying complex emotions—sincerity toward a loved one and wavering in the face of fate—with understated expressive power.

WOODZ, RIIZE, BIBI, Sam Kim, Hanroro, KiiiKiii, and others participated in the '21st Century Grand Duchess' OST, placing them high on major domestic and international music charts.
