Mostly/Entirely FxF, An isolated girl finds love

Something on the lighter side for my stories, loosely inspired by several different anime/manga series I have read/watched, and to a slight degree, my own life.  Would prefer a female partner.  While I obviously don’t have an issue playing girls or other guys doing the same, in FxF stories, I like at least one side of the story to be written by a woman.

On one side there is my character, a girl who has crippling difficulty interacting with others.  Says as little as possible.  Perhaps up to this point, never even said a word in class, few people outside of her family know her much at all.  Any interaction she has with people her age is largely limited to any sibling(s) she might have.

She intensely fears interacting with others, but is not happy about her likely future, friendless, alone, lucky if she even manages to find/keep work.  That’s where your character comes in.  At the start the characters are either complete strangers or know very little about each other.  Possibly classmates, maybe a friend of my character’s sister, something along those lines.  Something draws them together, and eventually they get closer.  First as friends, eventually more.

I don’t have a lot of the details figured out, it will depend a bit on who the characters are.  One or both of us could play side characters as well as wanted/needed, potentially of either gender (that’s where the possible MxF comes in, and/or the threesome/groups, though that could be left out completely).  It may or may nor get rather kinky when we eventually get to the sex, I’m rather open minded there, as seen on my preference sheet.
