IT'S YOU NEMO, YOU ARE (one of) MY FRIEND AND RP CRUSH(es) >:[
More broadly speaking, I'm a weird introvert that doesn't actually initiate social contact most of the time, and basically never unless I'm already comfortable with talking to that person one on one. I barely message those ones first anyway, but chat away with them no problem whenever they come and do extrovert things at me. Pahn can attest to this, for example.
Basically what this means is there are a bunch of people I'd like to be more friendly with but I'm a dork and don't do anything about it except poke them in group chats sometimes. A lot of the people who were staff pre-audit and hung out in staff chat fall into this category, like Nemo (the opening line wasn't just a joke 8D), Greenie, firejay, Shizuochan, Turtle, rissa, and more.
RP crushes are more a matter of not having the time to do things with everyone I'd like to play with, because I am shameless about prodding people in group areas to see if they're interested. Also messaging them one on one isn't a big issue because I'm fine with messaging people when I have something to actually discuss, because that's not random socializing that make my inner introvert screech. The list of people I'd go poke to see if they want to do a roleplay thing if I had time for more is similar to the above friend list thing, though most of them I've already done group stuff with before so it's not quite a matter of being like "omg I wanna roleplay with them but I never have," more like wanting to kidnap them for 1x1 things.
