It's about the National Health Insurance system. For a 'family' in Korea, the entire family members can get national insurance service if 'at least' one person in family works and pays for the insurance. However, for homosexual couples, it's not the case because they are not considered as 'families'. Now the court ordered so that the insurance policy is also applied to homosexual couples. It means, even if only one person is working and paying the insurance fee, another one (probably not working and not earning money) can get insurance benefit from this.
