the sibling line is pretty open! as it stands, she's the oldest between her and ~adiosmf, though there is room for older should it fit, but they were all born and raised in jeju before going their own ways for college. close knit despite sibling spats growing up, but pretty free form otherwise.
the co-owner spot is a college peer (snu for business administration) that decided to go into business with her to open this nightclub which has been around since 2011 or 2012, probably under a rebranding or two to not to stale, but its their baby, lol. the personal details of it are up in the air since i've never actually had someone fill it, but they're partners-in-crime, so to speak. this could potentially be merged with the sibling line if they're similarly aged. i have no issue with that at all.
