Lumi didn't exactly have a university to go to. He hadn't attended high school, either; they were more preoccupied with just surviving at that point. He'd been tossed between foster homes all throughout his childhood until they simply ran away to take things into their own hands, and so he'd only gotten a cheap apartment in the last couple of years. The time before that was spent on the street.
Besides their less-than-preferable 'upbringing', they were moderately successful at holding low-level jobs that didn't require prior experience or education. He'd worked a variety of jobs, and still did whatever he could get money for, but the coffee shop paid him a little better, so they spent more time there. Although his social skills did leave a little something to be desired at times, they could still be charming if they tried, and he often got very generous tips just because he was cute. They never tried especially hard to be, but, well… people like cats.
He looked up when he heard the bell on the door their ears twitching. He recognized Damian and started tapping at the screen in front of him. "Hello, Damian. I assume you're having the usual?" They asked, a bit dryly, but in a slightly sarcastic way that was (whether by intent or not) endearing. He wasn't typically one to remember customers' names, but Damian was a regular, and Lumi had grown a bit fond of him anyway.
