Starring Marife Yau and Sheena Chan as a pair of schoolgirls, the film explores their experiences while selling lingerie they have worn online and the unexpected attention they attracted.

Ching, a secondary school girl who struggles with stuttering, begins selling the lingerie she wears online for extra pocket money, encouraged by her best friend, Rachel.

Following Rachel's suggestion, they decide to expand their business by creating a fake account posing as a flight attendant, realizing that such pants can fetch several thousand dollars online.

Hurt by his reaction, Ching seeks revenge by posting photos of Lau and Rachel's meetups along with their conversation records about selling lingerie on an online forum.

[4] After co-writing Weeds on Fire (2016), screenwriter Riley Yip initially decided to leave the film industry to study aviation in Adelaide and pursue a career as a pilot.

[5] While awaiting her pilot examination results, she learned that the First Feature Film Initiative had increased its budget and winner quotas, and producer Steve Chan [zh] encouraged her to join the project.

[6] In the original script, both protagonists were physically disabled, one with a stutter and the other with dyslexia, but Yip found it challenging to portray their communication and subsequently changed their character settings.

[7][8] After winning the Initiative, Yip refined the screenplay with producer Fruit Chan during the COVID-19 pandemic, changing the ending from tragic to comedic in order to create a "lighter and more energetic" film that contrasted with the prevailing social atmosphere.

[29][30] Edmund Lee of South China Morning Post gave the film 2.5/5 stars, describing it as "a fairly unrealistic tale of misguided youth" while emphasizing its "perilous undertaking for young girls", and criticizing the writers for failing to fully utilize the "juicy premise", as well as calling the third act "contrived and out of character and remains largely unresolved", although he acknowledged Marife Yau's "charismatic performance" in her debut role, which he felt was "lessened by a story this lightweight and inconsequential".

[31] Alan Chu of United Daily News found the film to be a "clichéd commercial comedy" that lacks depth in its social commentary on female growth and empowerment, while also failing to deliver a light and amusing tone.

[32] Calvin Choi, reviewing for my903.com, argued that while films can effectively tackle morally ambiguous subjects and praised Sheena Chan's performance, Blossoms Under Somewhere fails to develop character motivations and explore moral dilemmas, particularly criticizing the protagonist Ching's "absolutely selfish" personality and noting that the story concludes in "a naive and contrived manner", suggesting that "the creators were incapable of wrapping things up".

[33] Ho Tak of Harper's Bazaar also offered a critical review and noted that although the theme and premise are intriguing, the narrative is imbalanced due to an excessive focus on Ching and Rachel's friendship, neglecting important elements like Ching's motivations and background, and rendering Adam Pak's character one-dimensional, ultimately resulting in an unsatisfying and incomplete ending marked by a slow pace and overlapping plot points.

[34] Amy Mullins of China Daily described the film as "a surprisingly assured and astute debut" from director-screenwriter Riley Yip, presenting "a delicately feminist coming-of-age story" that features strong character agency, natural performances, and a straightforward narrative style.

[35] Keith Ho, writing for HK01, also commended the film's unique exploration of teenage emotions and highlighted the impressive performances of Yau and Chan, but noted that it fails to fully leverage its themes of personal struggle and moral ambiguity, resulting in an open ending that may not resonate with all viewers.
