In the world of Korean webtoons, few titles spark as much curiosity—and controversy—as Secret Class. Written and illustrated by Wang Kang Cheol (writer) and Minachan (artist), Secret Class is categorized under the adult, romance, and drama genres, and it has gained massive popularity for its mix of risqué storytelling, expressive characters, and taboo-breaking themes.
Though not for everyone, the series has built a strong international fan base through unofficial translations and webtoon platforms. This article explores the premise, characters, art, themes, and reception of Secret Class, shedding light on why it continues to trend globally.
What Is Secret Class About?
Secret Class is a mature-rated manhwa that revolves around themes of forbidden desire, sexual awakening, and hidden relationships—often set within the confines of a seemingly normal household.
Plot Overview
The story follows Dae-Ho, a teenage boy who is adopted by his father’s friend after becoming an orphan. Though he is well taken care of, he remains naïve and clueless about romantic or sexual relationships—until the women in his new family begin giving him a very “secret class” in adulthood.
This unconventional and taboo subject matter drives much of the narrative, creating a mix of humor, drama, and explicit tension.
Genre and Format
Genre: Adult, Romance, Comedy, Drama
Target Audience: Mature readers (18+)
Format: Korean webtoon, released in full-color vertical format
Each chapter focuses on a slice-of-life style plot progression, with romantic tension and comedic missteps.
Release and Popularity
Secret Class first gained attention in the early 2020s via webtoon hosting sites and fan translation communities. Its engaging storytelling, graphic art, and slow-burn build-up helped it become a viral hit, especially among English-speaking fans.
Key Characters in Secret Class
One of the main reasons readers stay hooked to Secret Class is its well-drawn (both literally and narratively) cast of characters.
Dae-Ho: The Main Protagonist
A polite, innocent teen raised in a sheltered environment
Learns about relationships and intimacy in highly unconventional ways

Her internal conflicts and feelings create major story arcs
Other Female Leads
Secret Class features multiple female characters who each:
Represent different personalities—shy, confident, dominant, nurturing
Add layers to the plot through jealousy, affection, and competition
Often blur the lines between teacher, friend, and love interest
