The YouTube video associated with the announcement showed that the project included a pre-release single and two EPs.

The EP was released by 131 and Transparent Arts after B.I resigned his executive director position at IOK and reformed 131 as an independent label.

[12] The singer-songwriter developed that theme in his music videos through "a futuristic concept focused on the youth living in it, their love stories and rebellious moments".

[15] Through his global album project, B.I also intended to challenge himself by working with different producers and "tak[ing] on new styles of music".

[20] B.I stated that the message is "let's fall in love and completely dive into feelings we may grow to be cautious of as we get older".

[18] The opening song of the EP is the pre-release single "BTBT", whose title is derived from a Korean word that means "to stagger".

[12][21] "Keep Me Up", the second song and promoted single of the EP, is "about fierce love, but at the same time embodies the loneliness of the person who sings.

[23] B.I described the third song, "Middle with You", as a "cute and fresh" declaration of love, reminiscent of the color pink.

[24] Yet, he also called it a "more mature" song than "Keep Me Up", expressing an older narrator's wish to escape from everything through an innocent love.

It was named after a line from the movie, when the female protagonist, Clementine, dyes her hair orange and the main male character, Joel, calls her "Tangerine".

[26] The line "Okay, okay, okay, okay, okay" in the second verse is also a quote, from the single word "OK" said by Joel in the last scene of the film, after a fight with Clementine.

[35] Additionally, the playing cards convey the idea of love through photographs of B.I and love-related symbols, notably the recurring image of a rose, generally black and at times burning.

[38] A music video for the single "Keep Me Up" came out concurrently, showcasing choreography by Aitty Too members Youngbeen, Shawn and Beom.

[41] The documentary for "BTBT", I'll master the unknown and prove it to you, with B.I confessing his despairs and dreams, was released at 00:00 KST on May 22, 2022.

[47][48] He also promoted "BTBT" through Arirang TV's music program Simply K-Pop Con-Tour in June and July 2022 (episodes 524 to 527).

[49] From July to September 2022, he performed at fan meetings and festivals in South Korea and across Southeast Asia.

[52] In March 2023, he embarked on the L.O.L: The Hidden Stage tour, with six stops in Southeast and East Asia.

[53] In connection with his global album project, B.I collaborated with Ojeito and Arena Embroidery on a series of limited edition bags, titled "the pieces of love".

[57] More than 30,000 physical copies were sold through retailers whose sales count towards South Korean charts.
