Giorgia!!! I’m back from finals and I did really well. 🙂 I’ve seen this ingredient before I think. I’m learning so much from you, thanks. Even though my brain doesn’t retain all of the ingredients, I’m still picking up quite a bit.

And surprise! I picked up both color tattoo golds and the A+-rating-ones on temptalia the light pink one and the cream color all for you. :)) so don’t put those on your wish list haha. Your wish has been granted! As a genie, I grant you unlimited wishes hehe.
