Soyou from Sistar, now as your Chrome Theme ... do you need more than that to be happy?
Just a simple Soyou background with a watery design to follow the image.
The image was released by their official Facebook page and should not infringe any copyrights that I know off. Plus, this is huge advertisement =D
Best for fullHD, since a bigger image WOULD infringe copyrights.
You can also download a desktop wallpaper version of this at my gallery here: http://www.daisuki.com.br/album.html?id=11
