I'm a bit busy now, will have something up soon hopefully.
Kaori and Akatsuki should probably have met at least once or twice. Perhaps he eats where she works? Again, they're in the same school and I don't imagine it is a particularly big one so they would likely know one another exists. Or at least their face, but I don't know if there would be any further interaction? :o
And yeah honestly Kasumi being gay was so I can reference that comic in a later post. I live for it. I died when I saw the social links reference in the opening post. xD

I just thought him being gay was an excuse to name him after a flower. XD
