Seeing Eun Yu-jin’s “Sigma” series come out one after another reminds me of when I used to read “Japanese Dungeon” and “Chinese Dungeon” as serialized stories.

Every day has been so much fun, and even after two hours, I still couldn’t keep up with the real-time updates on Tamra, so I put everything else aside and just read Ridibooks and scrolled through Twitter—and I was so happy.

Whenever I think back to that time, I can’t help but feel truly grateful to the author.
