Girls' Generation's Hyoyeon released the first mood teaser just she had announced through her comeback schedule.

On May 10 at midnight KST, the singer released a set of teaser photos and the first mood teaser with the caption saying, "If I overcome disparagement by others with humility and modesty, it becomes the driving force for further self-growth. If you like and enjoy what's your own without being swayed by others' standards, then that becomes the standard of the world. This is my power that no one can take lightly."

She will be continuing to release teasers until May 16, which is the date when she will release the mini-album 'DEEP.' So stay tuned for more until then!
