Comment by Abdullah Jutt on Academy’s Undercover Professor - Chapter 118

The main storyline concludes at 727 without any romance. The side story features several potential female leads, including Rene, Flora, Sedina, Elisa, Selina, Queen Yekaterina Volsova, Empress Elieen, and Casey. For those curious about the inclusion of his students, the last arc had Rudger battling the world and stabbing Lumensis in the heart, which broke the cage that trapped them. This allowed him and Rene to travel to Earth/Korea, where he reunited with his Korean family. However, on their way back, Lumensis made a final attack that destroyed the bridge connecting the two worlds, forcing Rudger to sacrifice himself to save Rene. With support from Grander and others, Rene spent the next three years rescuing Mc from the Imaginal world/space between Dimenstion. In short, the side story begins after they rescue Heathcliff.
