NA is Nayeon's second solo Korean mini album, released June 14, 2024. The album title plays on the Korean word na (나), meaning "I" or "me," positioning it as a bolder, more self-assured statement than her debut — intentionally contrasting the introspective IM NAYEON with a hip-hop and dance-forward concept described by Nayeon herself as showing a "strong and mature" side previously unseen in her work with TWICE. The seven-track album features "ABCD" as the lead single alongside "Butterflies," "Heaven" (feat. Sam Kim), "Magic" (feat. Julie of KISS OF LIFE), "HalliGalli" (produced by Lee Chan Hyuk of AKMU), "Something," and "Count It." The album comes in nine physical versions: standard A, B, and C editions, a Digipack, a Platform Album NEMO (digital only, no CD), three vinyl editions (Orange Haze, Pink Haze, Blue Haze), and the limited A to Z edition — a distinctively packaged collector's version including a tarpaulin bag, newspaper, postcard, photocard (1/3), flyer, guarantee card, and card holder. Standard A/B/C editions include an 88-page photobook, 4 random photocards out of 15 types, postcard (1/3), hang tag (1/3), 8-piece track sticker pack, 12-page mini book, and folded poster (1/3), with a pre-order postcard set and poster. The Digipack adds a polaroid photocard. NA debuted at Billboard 200 #7, making Nayeon the first K-pop soloist in Billboard 200 history to place two different albums in the top 10. Circle Platinum certified (250,000+ copies) as of August 2024.
