[1] Prior to the release of "Rosenkrieg" in May 2021, a social media post by Loredana featuring her with a newborn child in her arms sparked rumors that the couple had reunited and married for a second time.

[6][7] The song was independently released for digital download and streaming on 28 May 2021 as the lead single from their collaborative studio album No Rich Parents (2021).

Swiss website Lyrics Magazin found the song "perfectly" backed by a "theatrical beat", which with the use of a vocal sample and an acoustic guitar, brought out the emotions even more.

[11][12] It features scenes of Loredana and Mozzik during their time together as a couple, including reenacted shots from their separation and reunion as well as the birth of their daughter.

[13] During Loredana's Red Bull Symphonic concert in November 2021, the single was presented in an orchestral version, which was labelled by Martin Seebacher, as a "banger".
