First Luv

"First Luv" is a song by the Filipino girl group Bini from their third studio album Flames (2025). The track was released as the second single of the album on October 2, 2025, through Star Music. It was written by Dwta, Kajo, Kiana Valenciano, Rosemarie Tan, and Shan Pooviriyakul, and produced by Kajo. "First Luv" is a mid-tempo bubblegum pop and R&B track characterized by its bright, upbeat melody and romantic theme. The song features a cowbell, 808 bass, and a church organ in its instrumentals. It marks Bini's first Tagalog lead single following a series of all-English tracks.

The song received favorable reviews from music critics, particularly for the members' vocal performances. In the week of October 18, 2025, the song entered Billboard Philippines' Hot 100 chart. It was reportedly the only P-pop track on the chart for the week. "First Luv" appeared in several listicles, such as "Pulp Loves: Our Favorite P-pop Songs of 2025" by the Filipino magazine Pulp and "P-pop's Best in 2025" by the American magazine Positively Filipino. In January 2026, the song also received a nomination for P-pop Song of the Year at the VP Choice Awards.

The music video was directed by Jason Max. It features the Bini members as Cupid's trainees, shooting arrows toward different individuals and instilling different forms of love in them: self-love, romantic love, platonic love/friendship, and familial love. LGBTQ stars Esnyr and Klarisse De Guzman appear in the video, among other actors. The video's visuals draw inspiration from rococo art. It also garnered acclaim, especially for its visual appeal and sapphic romantic storyline between De Guzman and her real-life partner Trina Rey.
