f(x) to release an OST for "Puzzle Bubble" on 8 February!

With the recent return of Amber, it looks as if f(x) is getting ready to re-enter the Kpop music scene! The music portal site Bugs! recently posted in their COMING SOON list a song by f(x).
The girls of f(x) are slated to release an OST on February 8th of this year. The OST is for the game Puzzle Bubble.
Puzzle Bubble is a game that was originally “puzzle bobble” when it was created in 1994. However, today it is popularized as Puzzle Bubble and is a game for all ages. The goal of the game is to gain points by directing a colored bubble using arrow keys, shooting it from the bottom of the screen to matching-colored bubbles on the other end of the screen, causing the connected bubbles of the same color to disappear. The game ends when the other end filled with bubbles reaches the launching area of the player, or when all the bubbles on the opposite end of the launch pad is empty.
