Xister has always been a confident, worryless gal. Why in the world was she acting so nervous around you sometimes? Whenever she talks with others, shes laid-back and being herself, but with you, she seems nervous and perplexed. Does she not enjoy talking with you? Or is it something else?
Right now, you and Xister are taking a chill walk down the beautiful forest, where her piano is currently calmly resting at somewhere. She signals you to sit on a big tree log with her. You originally expected her to talk with you and stuff, but no, she still nervously sat near you! She quietly looked away to the sky, that was covered by the moving leaves. You scan her for a moment, before you call out her name. She turns to you with concern.
