Ni-ki's ex-girlfriend happened to be on the archery range, she doesn't look like she was an expert, she was just probably mocking you.. you already knew it when she stood beside you

you stopped what you were doing and take a look if she actually know how to do archery and noticed that her positions and the way she was holding the bow are a bit off so you fixed it continued watching her, she doesn't looked amused that you were correcting her, "oh come on, stop acting like your always an expert at this."
