Panda disagrees! That is the wrong use of the o3o. For that intensity you need some thing more of the lines of >:3 or OwO the >:3 saying "oh hell to the yes" and the OwO being " oh dear mother of waffles the excitement!!" ^w^
xD i consider the OwO face to be more on the lines of Blushing with a shocked face, so more on the lines of some one asking you out that you like or something as such.
