I'm guessing she's ambitious, and will use everything she can to get what she wants. Including but not limited to her skills, and being a social chameleon to appeal to others around her to establish relations. Possibly for independence, recognition, to maybe to take over her household or gain accolades of her own to build a foundation for herself.Girl seems mentally unstable.
Serious at times, happy go lucky at others, annoying in the between.
MC clearly showe dhe doesn't like she prying around and being touchy touchy and she insists, if she was a savage fighter with a airhead personality I would accept it, but she is clearly smart and calculative, she is doing it on purpose, no idea the reason.
