“Ditto” serves as the pre-release single from NewJeans' first single album, OMG.

The lyrics for the track describe an inner discussion of a person falling in love right away, remiscent of being hit with Cupid’s arrow and who also tries their best to bravely show the affection to a significant one through a honest confession, while hoping for a pure and requited relationship.

Despite the sweet and vulnerable meaning, the Shin Wooseok-directed ‘side A’ and ‘side B’ music videos for “Ditto” revolve on a divergent story, as they are shot from the perspective of Heesoo (played by Park Jihu), a close friend and schoolmate of NewJeans.

The former shows the carefree and joyful life of the mysterious character and the group, which goes through an unexpected change after Heesoo’s arm is injuried and is hallucinating about her moments with imaginary friends, while the latter continues the storyline of the video and reveals how the actual, yet ideal mindset of the girl looks like.
