P1 is a woman. She has pink hair and wears a black and blue dress with blue and pink bow ties on the skirt, and blue t-strap heels. She steals the hat the boy has on. She resembles Eleanor Calder, Louis Tomlinson's girlfriend.

During the first and second choruses, the dancers don an autumn-esque appearance, in which their blue and pink attributes turn orange and yellow. 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.

Main Series
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 preformed

Just Dance Kids 2014
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 ends there.

Both: Stand still and make the number one with your right hand.

Trivia

 * This is one of the songs that is by One Direction to not involve a dance crew. It is followed by the solo routine One Way Or Another (Teenage Kicks).
 * It's 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 colours throughout the routine.
 * The glove colours also change four times for the girl and twice for the guy.
 * They seem to play a love story throughout the song.
 * Nothing about the dancers or background changes, except for the color.
 * This is the second One Direction song in the series. It was preceded by What Makes You Beautiful, and is followed by Kiss You, One Way Or Another (Teenage Kicks), Best Song Ever and No Control.
 * A move from Marcia Baila is reused in this routine.
 * The first eight pictograms show the girl with the hat and the boy with the bow tie, but they suddenly disappear.
 * The coaches for Me And My Broken Heart look very similar to the coaches for this song. However, they are not performed by the same people.
 * Both routines also have similar themes.
 * In the Just Dance Kids 2014 version, many lines of the lyrics miss some letters.
 * For example, Shot me out of the sky appears as hot me out of the sky.
