Chaeryeong's visuals are unique but that doesn't make her a visual hole

If she's a visual hole, then I guess I aspire to be a visual hole like her too.

She's the least good looking in her group, so visual hole.

And while she's not ugly ugly, she's definitely not amongst the absolute stunners that Kpop has to offer.

visual hole is someone who's less pretty or the least prettiest in a gp not ugly/unattractive.
