[7] The song has been described as a "high-octane anthem", with the use of "circus-like horns, ramped-up crowd cheers, and even random slurping noises".

[10][11][12] It depicts the group experiencing the exciting phase of liking someone during their youth, with scenes at a school, a basketball court, and a boxing ring.

Throughout the video, confetti and flower petals explode from the members, portraying the intensity of adolescent love.

[6][13] In the dance scenes, the group wears white shirts with suspenders, with "upbeat" and "well-coordinated" choreography, which Hoshi and the members took part in creating.

[16] IZM's Hong Eun-sol wrote that although the members "sing expressively as if they were acting", the song felt "somewhat disappointing" after the precedent set by "Pretty U".

Alexis of Kultscene noted that "while 'Pretty U' was a lovely song [...] 'Very Nice' is like taking a big bite out of a cotton candy ice cream on a summer day.

[30][31] In 2023, "Very Nice" was featured on MNET competition show Boys Planet as a battle mission for two teams to sing.

[32] In 2021, South Korean music streaming service Melon ranked "Very Nice" at number 80 on their list of the top 100 K-Pop songs of all time.
