All is well in the world of Akdong Musician (AKMU) because the talented sibling duo just dropped a teaser for their comeback.

According to a report by All Kpop, AKMU released the teaser trailer for their new music featuring a black and white video from the window of a running train. A few seconds into the teaser, the voices of Suhyun and Chanhyuk harmonize perfectly as the scene fades out. The brother and sister tandem is scheduled to release their comeback album on November 16.

The news of AKMU's comeback is a welcome development to fans who got worried that the siblings were not on good terms.

According to a recent report, netizens noticed that Chanhyuk unfollowed his sister on Instagram. Upon checking Suhyun's account, they were relieved to find that she was still following her brother.

While some fans were generally worried that the brother and sister got into a fight, there were even more fans who related to the sibling's squabble. According to some fans, if AKMU does not patch up soon, their mother will step in to force them to make up. Some said that Chanhyuk may have been annoyed by something that his sister did, promoting him to unfollow her on social media, All Kpop reported.

Even though the siblings do not always agree on everything, fans still found it sweet that Chanhyuk promoted his sister's solo "Alien" which came out last month.

It's been a while since AKMU made a comeback. It can be recalled that their last album "Sailing" was released in October 2019. The songs in the album made an all-kill in the Korean charts.

It was earlier reported that for AKMU's 2020 comeback, they will release three songs and three MVs. They will release one song per month for the last three months of the year, Kpop Post reported.

Suhyun kicked off AKMU's comeback season with "Alien" and two more songs are expected to follow.

According to YG, the new materials will be far more profound than AKMU's previous songs. This is expected to add another chapter to the artistic evolution of the talented duo. AKMU was signed by YG Entertainment after the second season of Kpop Star Season 2. Last year, at the height of the controversies surrounding the label, Chanhyuk said that they had no plans to leave the label because the people that they worked with were great people. He added their focus is to deliver great music to their fans, Soompi reported.
