Skool Luv Affair

Skool Luv Affair is the second extended play by South Korean boy band BTS. The ten-track album was released by Big Hit Entertainment on February 12, 2014, with "Boy in Luv" as its lead single. Two music videos, including a choreography only version, accompanied the single's release. A second single, "Just One Day", was promoted in April. Four different music videos were subsequently released in support of the song.

A limited edition repackage of the album, Skool Luv Affair Special Addition, was released on May 14, 2014. The physical copy of the repackage contained eighteen tracks, including two new songs: "Miss Right" and "I Like It (Slow Jam Remix)", and six instrumentals.
