I like how there's now this huge difference between the acronyms 'SGRA' and 'SGR' and which one is used for 'flirting' and which for 'romance' as if the 'A' is super important.
I figured the 'R' would be the key there.
SGR = romance
SGF = flirting
Actually SGR makes perfect sense to me as a catch all phrase for everything including flirting.
Flirting could be considered a romantic activity
The A of the SGRA acronym stands for Arcs, which would imply a story arc.
