At the third verse, they sport a Halloween-esque appearance, in which their outfits are black and orange, mainly the former. At the final chorus, their appearance is mainly of pink, yellow and purple.

The background seems to be a park. Far in the back are a Ferris wheel and city buildings. As the song plays, the background changes color, leaves starts to fall, the park levitates to the sky and the bench (the male dancer sat on), heart-shaped clouds appears, grass disappears while the light posts have light. In the chorus, the park has an autumn style with a heart-shaped sun and glowing hearts on the trees. During the bridge, the background shifts to a navy blue background with lights above the dancers. Then the heart-shaped sun appears but the park becomes purple and trees have the purple glowing hearts. At the end of the routine, a heart forms around the dancers when the final move is performed.

The routine starts with a bus dropping off the boy and the girl at a bus stop. They later head to a party and the routine.

 * This is the first One Direction song not to involve a Dance Crew. It is followed by One Way Or Another (Teenage Kicks), which is a Solo routine.
 * It is also the second One Direction song whose routine involves a female dancer; the first was the Extreme version of What Makes You Beautiful.
 * The dancers' colors of outfits change in the chorus, then change in the bridge, then switch to another different color in the last chorus.
 * The same goes for their pictograms, each switching to a record total of four different colors throughout the routine.
 * The glove colors also change four times for P1 and twice for P2.
 * The dancers seem to play a love story throughout the song.
 * The first eight pictograms show P1 with P2's hat and P2's with P1's bow tie, but these additional objects are no longer shown after the first verse starts.
 * The coaches' extraction appears to be separated from the background in the game files; however, during the bridge, the background merges with the coaches, making the mask just a white rectangle.
 * P2's shoes seem to be very glitchy.
 * During the bridge, the pictograms' arrows color depended on the dancer's glove color.
