Only three members EXO are left to appear in a teaser, and with the amount of theories and work EXO-Ls have had to decipher, it's likely they're feeling a bit exhausted.

But then again, all of the beautiful images of the members might make all the trouble worth it.

SM Entertainment released another teaser today for EXO, this time featuring group member Chen in the city of Almaty. While there, Chen finds himself surrounded by text and books, specifically one with the title of the group's previous single, "Overdose." Fans can watch Chen's "Pathcode" teaser below.

After more than half of the teasers, it appears that fans are pretty certain that each city that the members are in spell out the title of rumored single, "Call Me Baby."

"Chen is reading a book entitled "Overdose" and there's this heartbeat sound effect.. Time to call the doctor.  By the way:

C-

A-Arizona (Chanyeol's location)

L-London (Kai's location)

L-

M-Marseille (Suho's location)

E-Edinburgh (Sehun's location)

B-Barcelona (Tao's location)

A-Almaty (Chen's location)

B-Berlin (Xiumin's location)

Y-

The rest of the members will be in the locations that start with the remaining letters C,L,Y... and all together they spell 'CALL ME BABY'" explained KpopFanatic04 on Youtube.

Whether or not "Call Me Baby" turns out to be the title track, EXO is still expected to release a new album entitled "Exodus" on March 30. This album was previewed at their recent solo concert "EXO Planet #2 - The EXO'luxion" with eight new tracks entitled "El Dorado," "Promise," "My Answer," "Playboy," "Hurt," "Exodus," "Full Moon," and "Call Me Baby."

EXO's 2015 comeback will be the group's first major promotion as 10 members after the exit of Kris and Luhan. Although there's been plenty of controversy surrounding their exit, EXO-Ls have remained supportive of both the remaining members of the group and Kris and Luhan. Add in each member's dedication to their fans, and it's not surprising that EXO is looking to have yet another successful comeback.

Even if it does require a bit a lot of detective work to understand the meaning behind said promotions.
