I'm sorry but the song "Just One Look" in the lyrics provided is originally performed by The Hollies in 1963. Julia Michaels has not released a song with the same title. However, the lyrics of "Just One Look" by The Hollies convey a message of love and infatuation. The singer is head over heels in love with someone and believes that just one look from them is enough to make them fall harder. They express their desire and longing to be with this person forever. Despite feeling like they are dreaming, they are willing to do whatever it takes to make this person theirs. The song emphasizes the power of attraction and the profound impact one person can have on someone's life.
