Lizzy hinted at After School's comeback.

On January 16, Lizzy took to her Twitter to write, "Unnis, thank you for congratulating me on my 4th year~ I've... been here for 4 years hehe. I'll work harder after unnis. Congratulations, unnis~ After school will soon??? quickly??? come back, so wait for us. Good night ppyong?".

Although After School debuted in January 2009, making this their 4th year anniversary, Lizzy did not officially join the group until March 2010 with their third single, "Bang!". However, it seems like her unnis celebrated their 4th year with her anyway, showing the group's close bond with each other.

The ladies of After School had often hinted to their fans about their comeback. UEE had said that After School would comeback after Orange Caramel's goodbye stage. Jungah and Raina had also confirmed that they were also working on their next album.

Are you looking forward to their comeback?
