Barbie is a fantasy movie released in 2023. The film tells the story of a doll who lives in Barbie's kingdom and is expelled because of "imperfection" and takes risks in the real world. In the first half of the film, Barbie and Ken play the guitar and sing a song called "I'm just Ken". At that time, they were in Barbie's perfect world, dominated by Barbie, so the song they sang was called "I'm just Ken", which translated as "I'm just Ken".
