Later, at public recruitment and interview sites of the second season of "全民造星", performed "前傳" and the new song "破鏡" as seniors; captain 楊樂文 said being a judge that day was quite tense. On the night the season's final ended, first sang the new song "Reflection".

The music video of "Reflection" was directed by Taiwan director 陳勇秀, who has shot MVs for Jolin Tsai, Eason Chan, A-Lin and 潘瑋柏. Production of "WARRIOR" began with producer 陳浩然 collecting demos; 黃慧君 said the twelve members voted to use this song, passing by a large margin.

At the "2021年度叱咤樂壇頒獎典禮" held on January 1, 2022, "BOSS" received second place on the professional Ultimate Top Ten, and the group also received Best Group Silver and the My Favourite Group Award.

The second-anniversary concert "MIRROR "ONE & ALL" LIVE 2021" was issued as a two-disc Blu-ray, plus two photobooks of more than two hundred pages in all, recording on-stage performance and behind-the-scenes footage.

On July 28, 2022, at the fourth Hong Kong Coliseum concert, a falling-screen accident occurred, and two dancers were injured. Organiser and management company MakerVille stated that after the accident all remaining shows were cancelled, and pledged to bear medical costs and other aid for the three injured dancers 李啓言, 張梓峯 and 羅德智, and said support for Hong Kong dancers would continue, dancers being as indispensable to the show as MIRROR. The statement also said that when engaging the production team, qualifications and experience were the first consideration. A government working group found causes included metal fatigue leading to a steel-cable break, and that the LED screen's actual weight was heavier than reported; when hanger screws were installed on the LED screen frame, sleeve turnbuckles were not fitted to allow level adjustment.

At the "叱咤樂壇流行榜頒獎典禮2022" held on January 1, 2023, received Group Gold, and on stage sang and danced "Innerspace". 姜濤's English rap section in that song was written by 盧瀚霆; 姜濤 said of privately asking 盧瀚霆 about how to sing it; captain 楊樂文 explained the lyrics as exploring one's own universe, bursting new energy through understanding and digesting psychological and spiritual levels.

MakerVille said MIRROR debuted through 全民造星, started from zero together with the company, and the relationship is like family.

"MIRROR FEEL THE PASSION CONCERT TOUR 2024 • MACAU" ran four consecutive shows at Galaxy Macau Variety Hall, with the final show on May 19, 2024, the last stop of that world tour.
