After almost a month-long run of promoting their lead single, "Likey," off their first studio album Twicetagram, TWICE broke the news last week that they'll be releasing a repackaged album titled Merry & Happy.

The repackage will consist of two new tracks, including the next single, "Heart Shaker."

Making sure to not let their fans down with the end of "Likey," TWICE dropped a teaser to new their music video on Sunday, December 3 via VLive. The one-minute clip featured the nine members in white tees and jeans dancing to, what seems to be, the chorus of "Heart Shaker."

Merry & Happy is set to release on Dec. 11 at 6 p.m. (KST) and will mark as the group's fourth Korean project of 2017.

Check out the teaser below.
