[4] Jonghyun released the album through a variety of music sites on May 24 and officially began promotions with his appearance on Mnet's M Countdown on May 26.

[5] Jonghyun's fashion style for the promotions reflect elements of Shinee's known trend, including colourful outfits and skinny jeans, demonstrating a 1990s-inspired look.

[8] Jonghyun decided to emphasise storytelling on this album, adopting the persona of a "sweet, witty and sly" man who has fallen in love.

[6][11] "White T-Shirt" is an uptempo song that blends tropical house with urban pop and features a country-style piano melody.

Taylor Glasby of i-D labelled it one of the best releases of the year, praising it as "a remarkably cohesive experience that's both mature—such as the gloriously sensual track "Moon"—yet playfully able to pack the dancefloor ("White T-shirt")".

[9] IZM critic Jo Hae-ram noted that Jonghyun utilised his voice like an instrument to embody the character of each song; in "She Is", he changes his tone to match the electro-funk beat, while in "Orbit", his pronunciation is deliberately slurred and sticky.

Jo described the album as a "masterpiece of contemporary R&B", concluding that the "idol" label can be removed from Jonghyun.

[26] Kim Hak-seon of The Hankyoreh praised the album's consistency and was impressed by the collaborations with songwriters such as Deez.
