BTS's J-Hope is noticeable with his growth in this album. He discussed his 2 solo tracks in the group's new album, 'WINGS', during a press conference on October 10.

'WINGS', which is following BTS's 'School trilogy' and 'HYYH trilogy,' describes a story of boys who meet temptation, overcome them, and finally, mature into the next stage. They are boys no more and have added sexiness in their presence. 

BTS's title song, "Blood, Sweat & Tears" comprises a lethargic yet charismatic vocal and low-tone rapping, revealing a new layer of BTS's musical style. The song also captures the overall theme of the album well -- having to face the shadow of the evil and conflicts against the outside world as well as the coming-of-age experience. 

During the press conference, J-Hope happily shared, "I had the luxury of doing 2 solo tracks on this album... I got the baton after Rap Monster and SUGA, who did the intro track for the previous albums... I also worked hard on the choreography because it was very high-level this time."

He added, "I was happy to get compliments from the choreographer; I knew that my 'blood, sweat, and tears' weren't for nothing." 

J-Hope couldn't contain his joy as he shared, "We released the medley highlights because the album was released, but everyone was still excited for it....I am so happy. I love it."
