The song was written by Pdogg and RM , with Pdogg handling the production.
RM’s verses use vivid metaphors, such as comparing himself to spreading paint or noticing he is picking up the other person's speech habits: "To put it simply, I'm becoming you" .
Jungkook’s chorus captures the innocent, almost foolish nature of first love, describing how he feels "small" beside the person he likes and grins just by looking at them. Production Background
