Five Treasure Box is the fourth studio album by South Korean rock band F.T.

[1][2] Guitarist Choi Jong-hoon stated that the band "worked on everything from guitar rift, sound and song genre".

[3] Speaking of these tracks, bassist Lee Jae-jin explained that "it was too much of a waste to lock up our songs [in Japan]".

The band rewrote the lyrics in Korean and suggested to FNC Entertainment to include them on the album.

Drummer Choi Min-hwan explained that the band chose "the best" songs to rewrite, while taking the "album’s mood" into consideration.

They expressed understanding in the choice of FNC Entertainment wanting to promote a song with wider appeal, but the band showed preference over the tracks they composed.

[7] A music video teaser was revealed on September 6, which featured label mate Hye-jeong from AOA.

Island performed "Compass", "I Wish", and "Life" on Choi Hwa-jeong's SBS radio show Power Time.
