As with all Korean BLs,Semantic Error is short and intense. Only 8 episodes of around 20 minutes, but I felt that it was enough for the viewer to get a good sense of the characters and to get attached to the couple. The two leads have great chemistry and perform their character very well. The robotic and unsociable Chu Sang Woo and the adamant chaser Jang Jae Young are addicting to watch and I was never bored while watching. I think any BL or k-drama fan would enjoy this series.

On the other hand, I feel like this drama does not do much new to the BL genre as a whole. The friend group of Jang Jaeyoung is colorful, fresh, and is nice to see in a BL, but in terms of the plot, it does feel like a superficial story with unrealistic main characters. As someone who prefers BL movies and series with more believable characters, plots, and pairings, this makes me not rank it as high as another viewer. It's fun to watch but it is not my favorite trope, I'll put it like that. Ultimately I enjoyed the drama a lot and hope to see more from the two leads and I hope that Korea produces more BLs in the future.
