Best Teacher Baek Opens Season 4 With September 5 Premiere
Best Teacher Baek has a fresh, dated development for manhwa readers: WEBTOON lists Season 4 as beginning with episode 146, “Ancient History (S4 Premiere),” on September 5, 2026.
Season 4 Is Back
The confirmed update is straightforward. WEBTOON’s official listing for Best Teacher Baek shows “(S4) Ep. 146 - Ancient History (S4 Premiere)” dated September 5, 2026. The same listing places it after “(S3) Ep. 145 - I Personally Vouch For Him (Season 3 Finale),” dated December 24, 2025.
As of the September 14, 2026 publication date for this article, that makes the Season 4 premiere a recent return rather than an older catalog note. WEBTOON also labels the series as updating every Sunday.
What The Sources Confirm
The verified candidate data identifies Best Teacher Baek as a Korean manhwa, with AniList listing it under canonical ID anilist:142352 and Kitsu listing it as a current manhwa under ID 62310. WEBTOON credits Drawways, Rhy-Me, and Ganjjajang on the English series page.
Those sources confirm the return point, the episode number, the Season 3 finale placement, and the current update cadence. They do not confirm a Season 4 episode count, finale date, anime adaptation, or separate production announcement, so those details should be treated as unannounced.
For Nayovi Readers
For readers using Nayovi alongside a translate manhwa ai routine, the September 5 premiere is a useful bookmark because it cleanly separates Season 3 from Season 4. It is also the kind of update Android manhwa reader users may want to record when tracking official release schedules.
If your setup includes a translate manhwa apk or OCR-assisted reading notes, keep the official WEBTOON numbering as the reference: Season 4 begins at episode 146, not at a reset episode count.
