Secret Class (비밀수업), the massively popular and explicitly mature (R18+) romance manhwa written by Min Chan and illustrated by Wang Kang-Cheol, will release Secret Class Chapter 307 for English fast-scan readers next Friday, May 22, 2026.
If you have been keeping up with Dae-ho’s incredibly complicated living situation, you know the story revolves around a deeply naive orphan who was adopted by his father’s friend at age 13. Raised in a household of women, he reached adulthood completely unaware of romantic or adult relationships until his adoptive aunt and sisters decided to give him a “secret class”. Now deep into the 300s, the story has evolved into a massive, heavily intertwined harem drama where Dae-ho is maintaining secret relationships with almost every woman he knows, while trying desperately to keep them from finding out about each other.

Why Secret Class Chapter 307 Matters
The English fast-scan teams (such as Manga18FX and Toonily) have been rapidly updating to match the official Korean raws (which drop on Fridays). The recent chapters have focused heavily on Mia and the mounting tension of Dae-ho’s secrets finally catching up to him.
What makes Chapter 307 so critical? The fast-scan community has teased the upcoming chapter under the theme “Mia Was Shocked by What Her Mother Said”. Because Secret Class is an original manhwa (not based on a web novel), there is no source material to spoil the exact ending, but the narrative is clearly pushing toward a massive confrontation.
Secret Class Chapter 307 Spoilers
Because the fast-scan community closely tracks the original Korean releases on Toptoon, we have an outline of the upcoming events.
The Confrontation
Spoilers indicate that Secret Class Chapter 307 will heavily feature Mia reacting to a major revelation from her mother. For hundreds of chapters, the women in the house have been trying to keep their relationships with Dae-ho hidden from one another. Fans anticipate that the mother is finally going to drop hints—or openly confess—her involvement with Dae-ho, shattering the fragile dynamic of the household.
Dae-ho’s Panic
While the women are having their confrontation, the chapter is also expected to focus on Dae-ho realizing that his massive web of lies is collapsing. The comedic (and highly explicit) tension of the series relies on him juggling these relationships, and Chapter 307 marks a point where he loses control of the situation.
