4 Only
2021 studio album by Lee Hi

4 Only is the third Korean-language and fourth overall studio album by South Korean singer and songwriter Lee Hi, released on September 9, 2021, through AOMG. It is Lee's first studio album since Seoulite (2016), and first collection of new material since her 2019 EP 24°C and subsequent departure from YG Entertainment.
The single "Red Lipstick" featuring Yoon Mi-rae was released alongside the album on September 9. The album debuted at number 18 on the Gaon Album Chart in October 2021 following its physical release, selling over 8,000 copies in the last week of September.
Music and lyrics
According to the description of the album, the protagonist of 4 Only encounters different types of love in each track. The emotions frequently change within each track, expressing such things as the purity of love, sorrow, joy, sadness, thrill, anger, regret, excitement, and desperation.
To embody the theme of expressing the various emotions of love, Lee Hi incorporates various music genres on the album, setting her voice against synth-pop and jazz melodies rather than the funky R&B soul of her previous songs. The Latin-style song "Intentions" emphasizes her husky voice while "Waterride" adds a rhythmic guitar performance in a fast tempo. "Savior", the third collaboration between Lee Hi and B.I, includes jazz sounds and poetic lyrics. "Red Lipstick" is a retro-style song that "drew inspiration from the South Korean R&B and hip-hop duo Tashannie."
Singles
4 Only was preceded by the pre-release single "Only" on August 27, 2021, and was supported by the main single "Red Lipstick" featuring Yoon Mi-rae, released with the album on September 9.
The song "Savior" featuring B.I was scheduled to be released as the second pre-release single alongside "Only", but was delayed due to record production issues per a statement from AOMG. The music video for "Savior" was released on September 3, 2021, while the song was released on September 9, 2021, along with the rest of the album.

Why this record matters
“4 Only” is worth following because a concise public description often conceals a longer documentary argument. Here, Only, studio and album provides the most credible route into that argument.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Jan 21, 2026. The linked authority identifier is Q108276535. The first chronological checks are 2021, 2016 and 2019.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
