The lead single from 5SOS' third album tells the story of a love that never truly ends. It sees someone remembering his lover and admitting that, regardless of their separation, his feelings towards them remain the same. The song slightly drifts from their pop-punk origins into a more pop/electronic sound, as it swaps out distorted guitar sounds and breaking drums for catchier, cleaner melodies.

Teasing began on February 16th, 2018, when the band tweeted a black and white video clip with the word “BACK,” and their website was blacked out. This track marks the band’s return to music, dropping two years after their last album Sounds Good, Feels Good. Frontman Luke Hemmings takes the lead on this track with the other members provide backing vocals.
