Mono (stylized as mono.) is the second mixtape by South Korean rapper RM. It was released on October 23, 2018, through Big Hit Entertainment. It features seven tracks and was accompanied by an animated music video for the final track, "Forever Rain". RM has called Mono a playlist, while other publications have referred to it as a mixtape. It features songs sung and rapped in both Korean and English.

Background and release
RM first teased the mixtape and confirmed its production in March 2018 by posting a clip of an unnamed song through BTS' Twitter account. In June 2018, British electropop duo Honne said in an interview that they had possibly worked on music with RM. They initially gained an interest in collaborating with RM after discovering he was a fan of their music online, and meeting him in Seoul after performing there.

The mixtape itself was first announced on October 20, 2018, along with its track listing, album cover, and release date, through the Big Hit Entertainment Twitter page. The track listing was later shared by RM himself, with Mono described as a "playlist" rather than a traditional mixtape. It includes a track with production by Honne, as well as features the South Korean indie rock band Nell and singer eAeon. Mono is RM's second mixtape, following the release of his 2015 self-titled RM, and the first of his mixtapes to be released commercially.

Critical reception

MTV called the mixtape "equal parts wistful and weary, and the theme of loneliness is constant throughout", and said RM lays "his deep insecurities bare on songs like 'Tokyo' and 'Seoul'". Vulture stated "these tracks are the free therapy your body, soul, and bank account collectively require to ease into whatever fresh hell this week will inevitably bring", also saying Mono "sounds like how settling into a lukewarm bath feels: cleansing, just the right amount of steamy, and soothing to the touch". Vulture noted the mixtape contains "the slowest of bangers" and "moody bops", with RM whisper-rapping on "Forever Rain". Billboard noted the mixtape is more introspective than RM's first mixtape, labeling "Moonchild" a "smooth bilingual alt R&B track", "Badbye" as "sorrowful", and "Uhgood" "pensive".

Brandy Robidoux from Hollywood Life called "Forever Rain" one of his most honest tracks, with lyrics that state "When it rains, I feel as if I have some friends / You keep knocking on my windows and asking how am I doing / And I answer – I am still the hostage of life / I live not 'cause I can't die / But I'm still trapped on something". A writer from Billboard called "Moonchild" an ambient hip hop track that reflects on the pain of existence and solace found in moonlight. CelebMix described the Mixtape as, "The growing sensibility of an individual named Namjoon is clearly visible, making it a brilliant coming of age playlist of our time".

Accolades

Music videos
"Forever Rain" opens with a feeling of weariness and loneliness, with conscientious lyrics such as "I wish it rains all day / Cuz then people wouldn't stare at me / Cuz the umbrella would cover the sad face sad face / Cuz in the rain people are busy minding themselves." It is an animated video directed by Choi Jaehoon, who also served as creative director. The animation supervisors were Lee Jinhee and PD Gim Boseong, while editing was completed by Lee Jonhoon. The animators for the music video were Gim Boseong, Kim Bom, Kim Jihwan, Shin Dohyun, Ahn Jaeyoon, Yoon Jongha, Yoon Juri, Lee Jinhee, Jeon Soeun. Jeong dawoon, Jeong Jimin, and Hyun Yujeong.

The song "Seoul" is a lyric video, showing various famous places located in Seoul, such as the Han River, Cheonggyecheon stream, and Seonyudo Island. It features a brief shot of RM sitting in a car outside a convenience store and includes a short phone conversation where he describes his plans to leave. "Seoul" was directed by Choi Yongseok of Lumpens with assistant directors Guzza, Park Hyejeong and Jeong Minje, also from Lumpens. Nam Hyunwoo of GDW acted as the director of photography and Min Joonki of Sunshine Underground is credited with composition.

In the video for "Moonchild", lyrics such as "You say you wanna die but live it much harder / You say you wanna let go but put on another weight / Thinking of not thinking at all is still a thinking, you know" flash across a screen full of glitching lights, pixelation, and bright graphics. Tamar Herman from Billboard stated that it felt like the music video was "offering a sense of provocative solace, with a figure of RM visible at some points". The music video was also directed by Choi Yongseok of Lumpens with assistant directors Guzza, Park Hyejeong and Jeong Minje, also from Lumpens. Nam Hyunwoo of GDW acted as the director of photography and Min Joonki of Sunshine Underground is credited with composition. The construction manager was E Hyun Joon.
