Can confirm aha, this is faithful reposting because other sources of the bear comic date back to at least 2006, but this blog is the best location. Comics may need Google Lens to enjoy aha

This is another art site, it’s one comic per page and dated 2005, and names Go Byeong-gyu as the artist.

This is a Wiki page on the artist, and names cyworld.com as the original upload location, although cyworld seems to have since died.
