Ok, this is a hard thing to wrap up.
Irene really isn’t a who. They’re mostly a fictional thing I made up and even went as far as to name. I named them after Irene Adler because she (along with the much less backable John Watson)(Sorry newborn Sherlockians) was the only person asexual Sherlock Holmes ever really showed any interest in. And as an asexual, I wanted to name the person I have stronger (and heavily fictionalized) feelings for after her.
I would like to add that I have only really spoken to this person once and they haven’t shown any interest in me since. It’s mostly just a writer thing.
