The stand-alone digital single is the group's first original released in Mandarin only.
The singer models a number of high-fashion shorts-with-black-socks looks in the ads for the Italian luxury house.
The song comes as the K-pop star begins his service in the South Korean military.
The dynamic duo turn an abandoned warehouse into a daytime rave in the new clip.
"Even though I can't be with you physically, please know that I am having a good time with you in my heart," the star wrote.
The singers join Jin, Suga and J-Hope in fulfilling their mandatory obligation to country.
The pair recently dropped the remix of JK's "Standing Next to You."
The new release from ATEEZ brought in nearly 50% of the vote.
After getting a shout-out in BTS' "Butter," Ush makes it official with his soulful addition to JK's solo hit.
The new version of the song from the BTS member is due out on Friday (Dec. 1).
