This review contains spoilers for Vol. 4 of Semantic Error, published by Ize Press on November 18, 2025.
I read Semantic Error on Manta a few years ago, so some details are a bit fuzzy, but I also watched the drama adaptation. I loved all of them, but reading a physical copy is a completely different experience (especially with the uncensored panels—bless you, Ize Press). The physical edition also features Angy’s sketches at the beginning of each chapter.
I really liked the cover for Volume 4. It feels like a companion to the next volume, where it looks as if someone is taking Sangwoo’s photo—and now it’s revealed that the “someone” is Jaeyoung (not that anyone’s surprised). My favorite part of the design is the little avatar of Sangwoo falling through the sky with Jaeyoung’s iconic red jacket above him, almost as if he slipped right out of it. On the other side, near Jaeyoung’s head, there are tiny skull icons that show how dangerous he is to Sangwoo’s rationality. It’s such an adorable detail.
Vol. 4 is where Jaeyoung and Sangwoo’s relationship takes a step further, into a territory neither of them wants to think about. The two have sex for the first time. Then a second time. Then a third. And each time they fall into each other, something shifts in their dynamic, their desire for each other going beyond the physical.
Jaeyoung goes through an emotional rollercoaster in this volume, and it’s done through parallels. In an earlier chapter, Sangwoo nonchalantly says that he’ll have to find someone else to sate his physical urges once Jaeyoung leaves. It pisses Jaeyoung off, but he’s not sure why. When Sangwoo says the same thing later on, Jaeyoung’s anger is so much more palpable because he’s come to terms with his feelings. This time, Sangwoo’s words hurt him.
Likewise, Sangwoo has also felt the impact of the shift in his and Jaeyoung’s relationship. He smiles more now, and his laughter comes more easily. But the change has also sparked two emotions he’s never experienced before: jealousy and possessiveness.
The story has stayed focused on the two men so far, but we finally get more insight into Jaeyoung’s family. He has a twin brother named Jaehong, who couldn’t be more different from him, and he’s doted on by their grandfather, the head of the family. Although his grandfather clearly cares for him, Jaeyoung’s relationship with him is somewhat complicated. His grandfather gives him free rein—so long as he “keeps himself in line within the family.” In other words, Jaeyoung can do whatever he wants, as long as he doesn’t bring shame to the family name.
While this volume is packed with tension thanks to its many steamy (IYKYK) scenes, it also carries a stronger sense of looming doom. Both Jaeyoung and Sangwoo know their time together is limited, with Jaeyoung set to study abroad in just a few months. Jaeyoung tries to avoid thinking about it, while Sangwoo confronts it head-on with his usual logic, hoping to lessen the emotional impact of their inevitable separation. I have a feeling Volume 4 only offers a small glimpse of the obstacles the two will face as they try to figure out their future together.
Now that Jaeyoung has given his heart to Sangwoo, I can’t wait to see what Sangwoo will do with it in the next volume.
