With Exo’s comeback drawing near, the nine-member K-pop group is slaying the hearts of fans everywhere with online photo and music video teasers.

The group is slated to return with two new songs, "Lucky One" and "Monster," on June 9 for its third full-length album, titled EX’ACT. Exo dropped the music video teaser for "Lucky One" on Friday.

The preview shows six of the nine boys clad in white in what seems to be a panicked escape from a hospital. Nurses wheel away one of the members, D.O., down a hall on a stretcher. 

There’s a mysteriously dark and cloudy fluid in the IV, which some fans have speculated to be a nod to the other half of the comeback, "Monster." Considering members Lay, Xiumin, and Kai did not appear in this teaser, fans also expect they'll turn up in the second music video. 

Based on the teasers, the two songs take on opposite themes. "Lucky One" boasts colorful images of the members with undertones of '90s fashion, while the "Monster" photos reveal the members in shadowy lighting and dark clothing.

SM Entertainment spurred the comeback excitement last Wednesday with a confirmed time and date of the new songs and the reveal of Exo's new logo. Every release is accompanied by a new logo, and this time there will be two—one for each song.

The "Lucky One" logo sports a cute and rounded shape, resembling a lucky clover. It contrasts with the logo for "Monster," a hard, more traditional hexagonal shape—made of bones, no less.

Exo's comeback comes about a year after its second full-length album Exodus and two years after the mini-album Overdose. And of course, with the "Lucky One" teaser revealing a medical setting, Exo-L—Exo's official fan club—wasted no opportunity to connect it to Exo's iconic "Someone call the doctor" line from "Overdose."

In less than 24 hours, the "Lucky One" video teaser has already reached more than 1 million views. In the meantime, fans are anxiously waiting for the next teaser to drop.
