Background and release.
In December 2020, Yunho's agency SM Entertainment announced that he would be coming back with his second solo release. The EP's title, "Noir", was confirmed on January 4, 2021, and actress Shin Ye-eun's participation on the album was confirmed on January 5. From January 5 through 7, SM Entertainment released a series of teaser images featuring Yunho in "cinematic" backdrops, teasing the album's theme. On January 7, Yunho shared on his official Instagram a release schedule for the album, and introduced the album's cinema-inspired theme. Actor Hwang Jung-min was confirmed to be making an appearance in the music video for the EP's lead single, "Thank U."
Described as a "concept album", "Noir" draws inspiration from various film genres, including comedy, romance, sci-fi, and action. Music videos were filmed for each track in the album, telling different stories. In "Thank U," Yunho starred alongside Hwang and Lee Jung-hyun as rivaling gang members. The music video for the album's second promotional single "Eeny Meeny" starred Red Velvet member Seulgi, and in "La Rosa," Yunho and Shin Ye-eun played as love interests.
On January 8, Yunho dropped the album's first music video teaser and film poster for "Need You Right Now." On January 9, the "Loco (House Party)" set was revealed, and on January 11, "La Rosa" featuring Shin was released. On January 13, Yunho released the "futuristic" music video for "Time Machine," written by Thomas Troelsen. On January 15, the teaser images and character trailers for the lead single "Thank U" was dropped, followed by the prologue clip released on January 16. The full music video premiered on January 18, the day of the album's release.
Music and themes.
Described as a "concept album" by the "South China Morning Post", "Noir" is composed of six tracks, with each song representing a different genre of cinema. Each song from the album had its own reimagined movie poster and short film. 
"Time Machine" is the first track from "Noir". Inspired by sci-fi films, the song is a follow-up to Yunho's previous lead single "Follow" from the EP "True Colors" (2019), and is described as a "hyperpop" song that time-travels into an older world, which is the main universe for the next track, "Thank U." The song is written by Thomas Troelsen, who also co-wrote "Follow." The music video is directed by Seo Dong-hyuk. 
The second track and lead single "Thank U" is described as pop dance song with a "sense of darkness and weightiness," with a twist. It features a repetitive hook with conversational rap, with Yunho describing the song as the "epitome of [his] style." The lyrics talk about the determination of overcoming negativity, and thanking naysayers for carving a new path for him to walk on. The music video of "Thank U," directed by Kim Hyun-soo, stars Yunho as a gang member who survives an attempted murder by rivaling mafia boss Hwang Jung-min, and his right-hand man Lee Jung-hyun. Recovering from his wounds, he trains to exact revenge on those who betrayed him. Scenes and action sequences from the music video were influenced by western and eastern films such as "An Actor's Revenge" (1963), "Patriotism" (1966), ' (1985), ' (2003), "Oldboy" (2003), "A Bittersweet Life" (2005) and motifs inspired by Hong Kong film director Wong Kar-wai. The music video was positively received by general music critics. The Japanese version of "Thank U" was released on June 3, 2023 and was part of the set list for TVXQ's in Japan.
The third track "Eeny Meeny" was released as a separate digital single on January 25, 2021. Described as a monodrama romantic comedy piece, the music video of "Eeny Meeny" also features a performance by Red Velvet member Seulgi. The song is a dance track with funky beats. The music video is directed by Shin Heewon.
The fourth track "Loco (House Party)" is the album's comedy piece. Also co-written by Troelsen, "Loco" is described a "funky" dance pop song with disco house beats. The music video is directed by Rim Haansol.
The fifth track "Need You Right Now" is described as a monodrama that conveys the message of carpe diem. The music video is directed by Jason Kim.
The final track "La Rosa" features South Korean actress Shin Ye-eun, who is also featured in the music video. Directed by Yua, the video stars Yunho and Shin as two lovers who think about each other through the night.
