The song's title was initially announced as "Love Wins" on January 15, 2024, before being changed by IU's label Edam to "Love Wins All" before release due to criticism that the title was already in use as a slogan to commemorate the United States legalizing same-sex marriage in 2015.

The video was criticized online for its depiction of disabilities, as IU is shown as having a hearing impairment and V as having a visual impairment. The pair find a camcorder through which they are able to view the other without their respective disabilities, which was considered to be "discriminatory" as it implies disabled people "admire and fantasize" about not having their disabilities.

本动画筹备超过十年，场景取材自德国古镇讷德林根（Nördlingen），使用芭蕾舞、古典音乐、童话故事、北欧神话与欧洲民间传说作为整个故事推进的原动力。每个角色都有一首古典乐作为主题曲，每集更是选定一首或一个芭蕾舞剧或歌剧的曲目作为主题曲，以表示本集剧情的主导动机。曾经使用过的芭蕾舞蹈及音乐包括天鹅湖、胡桃夹子、睡美人、展览会之画、动物狂欢节和尼伯龙根的指环等。
