Reilly's first single, "Ur Only",^[6] was written while still in Paris,^[2] and her second single, "Love Online", a song about online relationships, was released in April 2021,^[6] and became a finalist in Prospect 100's Global Music Competition the following month;^[7] the month after that, she released "Little Tescos",^[8] a song about Tesco Express, the only place she could go in lockdown.^[9] She then moved to London for university, and released "Lost in Translation",^{[10]: 1:01:38} a hyperpop song^[11] about dating a French boy,^{[10]: 1:01:38} which began with vocal samples,^[12] and made reference to Google Translate, struggling with abbreviations, and Brexit.^[13] On 24 June 2022, she released Imaginary Girls,^[9] an EP consisting of six songs and two interludes including "Love Online" and "Lost in Translation",^[11] which was less than fifteen and a half minutes long,^[9] and dealt with the internet, lockdown relationships and social media.^[14]

She then moved back to her parents' house, and wrote her second EP,^{[15]: 1:09:24} *For Entertainment Purposes Only,^[16] in July and August 2022, with the songs being produced after she met her producer in October^{[15]: 1:09:24} and set up "Coupdekat camp", where they locked themselves in her room for a week to work on it.^[17] In February 2023, she released "Superglue", an alt-pop song^[18] about a boy who kept entering and exiting her life and which addressed codependency and red flags.^[14] The following month, she released "Babyteef", a semi-autobiographical song about growing up too fast as a result of social media^[19] which used premature removal of deciduous teeth as a metaphor.^[20] She then released "It's Not You" in May,^[21] for which the vocals were recorded while trampolining on her bed,^[22] and then the EP in June, which featured "Stunt Girl".^[23] In August 2023, she played Leeds Festival as part of Climate Live.^[24] She was booked for the 2024 Great Escape Festival in Brighton, but dropped out after committing to the Bands Boycott Barclays campaign, whose participants refused to play the event while its sponsor continued to bankroll companies supplying weapons and military technologies to Israel.^[25]

In May 2022, she met fellow musician Maisi for brunch^[26] after she discovered Reilly via TikTok;^[27] there, they discussed the loneliness of being a woman in the music industry and how they were often pitted against each other.^[26] This prompted the pair to set up a group chat^[27] on WhatsApp^[28] called Ladies Making Noise in London for the women and non-binary musicians they knew at that time.^[27] Initially starting with ten musicians including Piri^[27] and Matilda Cole,^[29] the adding of other members caused the member list to grow to forty people, prompting them to set up an Instagram page, Loud LDN.^[26] Reilly used a June 2023 interview to note that the chat had 120 members and that it had moved to Discord.^[30] On 4 November 2022, she supported Piri's band Piri & Tommy at Komedia on the Brighton leg of their Froge.tour.^[9]
