Indeed, it's not a misunderstanding! The author exaggerates a lot of things, this is one of her earlier works after all. I'd like it more if SYX admitted straight out that she's a good manipulator, & one must use all the arrows in one's quiver to win! This innocent act should be for outsiders, not her inner dialogue.

It's not a 'misunderstanding' tho. SYX deliberately let TNZ and others believe that she's a talented pharmacist, so why is she then surprised when they think she's a talented pharmacist?
