Last November, the world took notice of the rising popularity of the rookie girl group, P1Harmony (Saina, Aran, Keena, and Xiou), who debuted with "The P1Harmony". Their first single, "Breakthrough: Cupid," released on February 24th, entered the Billboard Hot 100 chart and set a new record as the shortest time for a K-pop group to do so, only six months after their debut. Since then, they have been breaking new records every week. They are a rebel among K-pop groups, being a rookie girl group from a small agency, and their success has been garnering global attention.

P1Harmony's "Cupid" rose to 19th place on the Billboard Hot 100 chart, up 22 spots from the previous week. Currently, the K-pop girl group song that has spent the longest time on the Hot 100 chart is "Ice Cream," a collaboration between BLACKPINK and American pop star Selena Gomez, which stayed on the chart for a total of eight weeks and reached a peak of 13th place.

The rise in rank shows that P1Harmony's local popularity is not just a fleeting trend. After first entering the chart at 100th place last month, they steadily climbed up the rankings to 94th place in the second week, 85th place in the third week, and 60th place in the fourth week. In the fifth week, they reached 50th place, and in the sixth week, they climbed to 41st place. As "Cupid" continues its steady rise, the possibility of achieving the longest-running record for a K-pop girl group on the Hot 100 chart is growing.

If P1Harmony enters the chart again next week, they will tie with BLACKPINK for the top spot. It is also possible for them to break the record for the highest ranking achieved by a K-pop girl group, surpassing "Ice Cream"'s peak of 13th place. "Cupid" is particularly significant because it is a solo track by P1Harmony and not a collaboration with a pop star like "Ice Cream." As a result, "Cupid" is the highest charting song by a female K-pop artist in history, based on pure artist performance.
