I'm pretty blind to KKM too but reading his backstory I definitely agree with this! Luke could use kind of a lowkey stoic presence around and he could also be good at getting Gwendal out of his shell a little since Luke's kind of all over the place with things he does and where he spends his time. He'd really appreciate repeat customers and those are definitely the people he'd be most likely to befriend anyway. And hey, since he's no longer a bouncer he's gotta have somebody take over.

This sounds good to me for starting them off!
