Here's something interesting for you: When Koong was released prior to the main MVs, it was a direct parallel to Ateez' first comeback. Hala Hala was released first as a performance video, same as Koong. And i feel that the white "Tricky" attire is a reflection of the Halateez Black outfits, providing a little Yin/Yang and also possibly providing a deeper connection to their brothers, seeing as Xikers are travelling through time and space searching for coordinates, multiverse theory would suggest that they could inevitably find themselves in universe A or Z
