PlayM Entertainment released a music video teaser for the title song "Holiday Party" of Weekly's fourth mini-album "Play Game: Holiday" on its official social media and YouTube channel at 6 p.m. on the 2nd of August.

About 40 seconds of music video teaser video caught the eye as Weekly, who gathered with tickets for "Galaxy Train," enjoyed a unique "holiday party" with table-filled party food, hide-and-seek, and board games. In particular, the cheerful rhythm throughout the teaser heralded strong addiction, and the short new song and group dance in the video stimulated curiosity about the new unique performance that Weekly will present, following the performance of the previous "We" series.
