The 'trusted listen' group FIFTY FIFTY has stepped up as the first OST singer for tvN's new Monday-Tuesday drama 'I'll Go to Work Tomorrow!'. FIFTY FIFTY's 'I'll Go to Work Tomorrow!' OST Part 1 will be released on July 23 at 6 p.m. through various online music sites. The track will be available to stream starting at 6 p.m. on the day of release. The title track 'My Wonder' is a song that blends dreamy synth sounds with a medium-tempo rhythm. It expresses the excitement and comfort of the moment of falling in love through FIFTY FIFTY's signature clear and emotive vocals, heightening the immersion of the drama. This OST album features not only the title track but also 'Hopping,' an opening theme song embodying the heart toward a new beginning, and 'Ice Princess,' which highlights member Hana's transparent vocal tone, promising listeners a diverse musical experience. Meanwhile, the drama 'I'll Go to Work Tomorrow!' depicts an office romance between a seventh-year office worker who has fallen into a routine slump and a prickly boss. The series is generating anticipation as it portrays the realistic concerns and growth of office workers. Debuting in 2022, FIFTY FIFTY sparked a challenge craze last year with 'Pookie' and entered the U.S. Billboard Pop Airplay chart with 'Skittlez.' They recently released their fourth mini album 'Imperfect-I'mperfect' and continue to be actively promoting. Photos provided by ATTRAKT (artist image) and Studio Dragon·TOON STUDIO (album cover).
