Is it common for Korean men to like girl group content?

In recent years, while traveling to various countries in East Asia, I met Korean friends and exchanged Instagram accounts. During this process, I observed that some Korean men follow and enjoy various content, not only music from girl groups but also interviews and dance videos. In the country where I live, this phenomenon is not common, so I am curious if such activities are typical among men in their late 20s to early 30s in Korea. I would like to know how this interest is perceived in Korea. Is this interest considered natural for many people, or is it regarded as a special hobby?
