Family friendly clinics in Seoul?

I’m planning to go to a clinic in Seoul with my family we’re a pretty big group (10 people total, 8 adults and 2 kids). We all want to get a variety of treatments done.

I know most clinics operate one by one, but I was wondering if there are any places that can accommodate larger groups like a private room where multiple people can be together, or at least rooms close to each other. Just curious if anyone has heard of clinics that do this.
