Just because it's successful, doesn't mean it has to be 150 chapters. I liked this chapter but the focus should be even more on the main couple now that it's going to be a monthly release.
This side couple doing the same reheated tropes as the main pair gives me flashbacks to
"Kaguya-sama: Love is War". I followed Ishigami and Iino's love story with great interest, only to be hugely disappointed in the end, because they started playing the same game as the main characters, leaving me with an open ending and no sense of closure. Not interesting, but really frustrating IMO...
