But, because Ariel was arrested in 2010, both "Separuh Aku" and its music video's release were delayed. The video depicts Noah's vocalist Ariel portraying personifications of his dark and light sides and Indonesian actress Gista Putri portraying his girlfriend. The music video for "Separuh Aku" was directed by Nicholas Nicky. Seperti Seharusnya was released on 16 September 2012, with "Separuh Aku" as its third track. It was the first single from Noah's first album Seperti Seharusnya and their first single since Noah announced their new name. Noah released "Separuh Aku" as a single on 3 August 2012 via airplay on 200 radios in Indonesia. A demo version of the song was leaked in 2010, but Noah's guitarist Uki stated that the song has been re-recorded to make the final version different.
David described "Separuh Aku" as a song themed around empathy. David said that he came up with idea for the song after listening to his friend confiding in him. "Separuh Aku" was written by Noah's keyboardist David and Noah's additional bassist Ihsan.
