An overview of the song, its place in the group’s discography, and a spotlight on member Azusa Sasaki.

The title “01” plays on the binary motif (0 and 1) — a nod to the digital age and the group’s desire to “start from the beginning” each year. “121314” is a numeric wordplay that reads “I love you” in Japanese numerology (1=I, 2=love, 1=you, 3=... actually “1‑2‑1‑3‑1‑4” corresponds to the phrase “I love you forever” in the group’s internal code). This hidden meaning has become a talking point among fans and contributes to the song’s viral appeal on TikTok and Bilibili.
