The music that left a lasting impression during the highlight scenes of “21st Century Grand Prince’s Wife” is finally being officially released as an OST!
Kakao Entertainment announced that OST Part 10, “Is the Way I Love Wrong?” by Lim Jung-won (Son-eul-mo-a), will be released on May 9 at 6 PM. The song delicately captures the heartbreaking emotions of Seong Hee-joo (played by IU) and Grand Prince Ian (played by Byeon Woo-seok) as they hold onto each other despite extreme crises.
From poisoning attempts to the leak of their marriage contract, Episode 8 was packed with tension. This OST played during the dramatic hug after Seong Hee-joo woke up during the wedding, and again in the ending scene where Grand Prince Ian protectively shields her from reporters, sending fans’ hearts fluttering worldwide. Then, in yesterday’s Episode 9, the song amplified the sorrow as Seong Hee-joo told Grand Prince Ian, “Let’s divorce,” to protect him from growing criticism.
“Is the Way I Love Wrong?” is a ballad centered around a calm piano melody. Vintage guitar textures and subtle string sounds add a serene atmosphere to the track. Lim Jung-won’s restrained vocals gradually build the emotion, beautifully expressing a love that lingers and never fades.
Lim Jung-won, the frontman of the rising indie band Son-eul-mo-a, took part in writing, composing, and singing the track to ensure its quality. While he is known for the powerful rock sounds of his band, he showcases a different musical side here by delicately handling emotional nuances. His sincere vocals and lyrical melody prove his potential as a singer-songwriter.
The OST for “21st Century Grand Prince’s Wife” features artists from various genres, creating different emotional layers. From bright, fluttering moments to the complex feelings of the characters, the diverse music is heightening the immersion of the show. This latest track is being praised for capturing the intimate emotions of the leads, especially during scenes where Grand Prince Ian’s feelings reach their peak.
