Alright, then it's safe to assume that Gaku and Alex would have met each other, due to occasionally working at the bar, don't really know each other that well.

Anyway, I'm going to sleep soon (it's 1:50am here), and I won't be able to access a computer until tomorrow evening, so I'll leave a few short notes for everyone else for the sake of ideas -- sorry they're not longer, kinda tired. Although I should probably note that them being acquainted with each other is largely dependent on if they visit the bar much.
- Henry: would probably immensely enjoy the company of him -- his relaxed nature would probably decrease some of stress that talking with people usually brings her.
- Everett: would probably be daunted by his intelligence, but overall similar to her reactions to Henry.
- Eli: Alex would view her as being this big challenge in overcoming some of her lacking social skills, like if being able to talk to that unapproachable and mysterious girl would mean that she'd be able to talk to anyone. She would be very interested in meeting with her, but would currently be far too scared for it.
