Backed by a piano, the soul and R&B song draws some influences from 1990s rhythm and blues, with lyrics about moving on from a difficult relationship.

In an interview with Billboard's Adelle Platon, K. Michelle said that the song is "about those last steps that a person takes after a breakup: when you can acknowledge the importance of the relationship but also see that you're better off alone."

"[7][8] Writing for HotNewHipHop, Kevin Goddard wrote: "Kicking off the album campaign, the R&B singer decides to come through tonight and share her new single called "Not A Little Bit"."

He addedː "Going over the piano-laced production, K Michelle delivers a heartfelt ballad that finds her singing about moving on from her past relationship and not looking back.

"[11] The song was applauded by Idolator as "a welcome return to the music scene" for K. Michelle, adding, "The first taste of the R&B diva's third LP is a soulful ballad that showcases her powerful pipes and fiery attitude.

[13] Elle Breezy of Singersroom gave the song a positive review, saying that Michelle showed that there is "life after a tough breakup" and also said that the pre-chorus seemed very relatable.

If K. Michelle came out ten years ago, when this style of music dominated the charts and reality shows weren't about who could get into the most fights per episode, she'd be a legend by now.

[18] It was shot in Atlanta, Georgia[19] The video features K. Michelle walking, bathing, and even drinking Jack Daniels in the rain as she reflects on her bad relationship.

[25] During the second verse, Michelle walks into her living room and sits down on the couch as she pulls out a bottle of Jack Daniel's whiskey and pours it into a cup.

Another rain cloud comes into the ceiling of the living room and begins pouring over her head as she is sitting on the couch, causing her mascara to start running.

Michelle then walks into her living room in a white wrap dress as she packs her ex lover's belongings along with a picture of her and him in a duffel bag.

[30] Bianca Gracie of Fuse called the music video an "empowering visual" and said that it gives the song an extra dose of drama.

[28] Ken Hamm of SoulBounce said that the clip showed a bit of the creative side of Michelle, adding that it was "far and away better than most of the basic music videos that come across our timeline.
