SF9 has officially started their image teasing.

The first batch includes 'hidden emotion' version teaser images as well as leader Youngbin's teaser images. The boys are going for both a charismatic and soft look this time around, which is quite a turn around from their last comeback with "Mamma Mia".

Also, just like yesterday with Youngbin, the SF9 official Twitter page has changed their display to Rowoon, which you can also check out below.

Coming up next tonight at 9PM KST is Rowoon, so stay tuned for his teaser and all the way up to July 31st for SF9's comeback.
