About Semantic Error Manga

About Semantic Error Manga

Semantic Error Manga was first released in March 2021 and has only grown in popularity ever since. The second season ended in April 2022, and fans have been looking forward to continuing the love story on campus. The long-awaited third season will be available to read exclusively on Manta Comics in September.

Semantic Error Manga follows the story of college students Sanu Choo and Jaeyoung Jang. As a computer science student, Sangwoo lives by following the rules. For him, there is usually a logical solution to every problem he faces until he meets Jaeyoung, who is the exact opposite of Sun. Jaeyoung is loud, and rambunctious and seems to want to hurt Sana at every opportunity. For Sangwoo, Jaeyeon is a “mistake” in his life that he is determined to get rid of, but as they grow closer, their relationship evolves from one mistake to something more.

Adaptations of BL’s Korean webcomics have become increasingly popular as of late, with many fans feeling that it is indicative of a subtle change in the public’s attitude towards the genre. The semantic error received further attention when a dramatic adaptation was released in February 2022 and can be viewed on Viki in the US and internationally. The show was a huge success both domestically and abroad and was even screened at the 26th Bucheon International Fantastic Film Festival (BIFAN), where it received a warm welcome.
