Released on Tuesday, the track opens with airy strings and Soyou’s breathy voice before morphing into a rhythmic pop song that incorporates tropical house synths and R&B melodies as Key professes his dedication. Known by his stage name but born Kim Kibum, Key will reportedly follow up “Forever Yours” with his first solo album later this month.
The song was released through a throwback music video that sees Key as a car mechanic who takes an interstellar trip in his suped-up, flying Mustang. With colorful, retro-feeling graphics and word art flashing across the galactic scenes, the clip ends with Key landing in a desert and looking around. While she can be heard, Soyou — who has previously spoken about her close friendship with Key — does not make an appearance in the video.
While it’s his first formal track as a soloist, Key has previously worked with numerous other artists on collaborations and been featured on television soundtracks; in 2014, he formed a duo known as ToHeart with INFINITE’s Nam Woohyun. Earlier this year, Key was featured in a remix of Years & Years’ “If You’re Over Me.” He is the third SHINee member to release a solo album, following Jonghyun and Taemin.
Key recently garnered a lot of attention in the K-pop world for his dedication to his costume on Halloween, when he dressed up as the Harry Potter series’ primary antagonist Voldemort.
As a member of SHINee, Key has seen over 10 albums appear on the World Albums chart. Formed in 2008, the group celebrated their 10th anniversary earlier this year with The Story of Light album series, the first of which peaked at No. 4 on the World Albums chart dated June 9.
