The Rise in Queer/BL Adult Webtoons in Korea
Queer/BL (Boy Love) adult webtoons are surprisingly very popular in Korea. Even more surprising is that straight Korean female are the main readers. In addition, many queer webtoon authors are female. Most queer adult webtoons focus on homophobia or discrimination against queer people in Korea. These forms of homophobia come from family, friends, or coworkers. Therefore these queer webtoons offer more serious content that is also educational. Therefore many queer/BL webtoons have overwhelming fan support. Many fans have expressed that queer/BL webtoons helped them understand sexual minorities and overcome their prejudices. You will find a few queer/BL webtoons on the list, and we recommend you try them.
Painter of the Night
One of Korea’s most popular adult webtoons, Painter of the Night is the biggest title on Lezhin Comics. The story follows a talented young painter, Na-kyum, in feudal Korea. He is very shy yet determined with a big heart. Once renowned for his erotic male paintings, Na-kyum has since quit painting. That is until a young nobleman named Seungho comes into his life and demands more paintings. For which he is more than happy to pay and model. This webtoon’s art style sets it apart from the others. In addition, the character of Seungho is one of the more in-depth characters around. He loves power and sex, making it difficult for readers to cheer for or hate him.
The art style is unique, and the characters’ expressions and the webtoon’s coloring really separate it from the rest. It is a great representation of lust and love in historical times while also showing Korea’s social power structures and value systems.

BJ Alex
Dong-gyun spends his days in class and nights behind a locked door watching his favorite cam boy streamer, BJ Alex. Alex is a very shady character who takes advantage of Dong-gyun sexually. Alex uses his celebrity power to control Dong-gyun who obeys Alex’s commands. Soon the balance of power shifts as Alex develops strong feelings for Dong-gyun. What started as purely a physical relationship (sex partners) has the potential to develop into something more.
Once you understand the character’s backstories, the webtoon is easy. While many feel the story is too predictable, the characters are what many readers like about BJ Alex. The characters are always exciting and detail how the characters went from a purely physical relationship to something more.

A Man of Virtue
A Man of Virtue is about Nam Jinwoo. He spends his whole life coming in second place at everything. From school competitions to his work life, Ma Sangtae has always been able to run faster, be smarter, and take the initiative. Jinwoo hates Sangtae. He has been living in the shadow of Ma Sangtae, his whole life. It started in High School, then on to College, and now at the office. And as we all know in these comics, hate turns to lust. The lust turns when Jinwoo finds himself cursed with the dirtiest, most erotic fantasies of Sangtae. He can’t control these fantasies because they are not his fantasies, but he is convinced they’re Sangtae’s fantasies.
For those looking for a bit of humor in their adult webtoon, A Man of Virtue is for you. It is a lot of fun and cute while still having NSFW graphics. The first five chapters of this Manhwa are free on Lezhin, and for those that pay for the whole thing, I can promise a lot of really touching moments about relationships, adulthood, and, most of all, coming to terms with your sexuality.

Talk to Me
Talk to Me is about Raeyim, who has it all. She’s beautiful, smart, classy, and has a wonderful boyfriend. And it’s not by accident, no. It’s by careful design and management of her reputation. No one would suspect she spends her nights watching porn and wanting something more… from sex. Her boyfriend’s fine, but she doesn’t want him to ask if he should go down on her. Everyone considers Raeyim to be the purest girl ever to walk the earth. This adult webtoon is cute, fun, and, most of all, sexy. You will get a deeper insight into a woman’s mind and see female sexuality and their desires/lust openly and without reservations.
For those who don’t like a lot of drama in their adult webtoon, Talk to Me offers a series where couples explore interesting sex ideas such as BDSM, Roleplaying, Vibrators, phone sex, etc. Therefore, the series does not have a lot of smut and remains healthy and non-toxic. Add this to a well-written storyline, and you have the top non-BL webtoon on this list.

Love is an Illusion
Ask any fan, and they’ll tell you the Omegaverse is weird. As Lezhin Comics’ first English language foray into the genre, it’s… intense. Hye-sung has been convinced he’s an Alpha at the top of the food chain. But everything goes sideways when he realizes he’s an Omega! After this revelation, he continuously crosses paths with Dojin, an Alpha who can’t stand Omegas. In addition, in the Omegaverse, Omegas can give birth. That’s right, guys can get pregnant.
The art here is in color and amazing. Then you add the roller coaster of emotions you will feel for the characters, and you have one great adult webtoon. The almost non-consensual sex scenes might turn many off, but the book’s second volume is even better than the first.

Love Shuttle
From the acclaimed author and artist of An Easy Target comes Love Shuttle. Doyun is tall, handsome, and beautiful. Everyone assumes he’s an Alpha, but he’s an Omega; he’s just never gone into “heat” before. He is considered a late bloomer, and his body is ready to bloom; all he has is his work rival, Taehan. Taehan is happy to take advantage of the situation and offer his *ahem* “help.” Taehan is a more likable Alpha than most traditional Alphas and the most interesting character in the series.
This is one of the few omega verse webtoons that does not contain an abusive relationship. While the artwork is not the best, the story has a lot of comedy while also being steamy.

She takes a minute to “enjoy” herself until she realizes there’s a man on the train! Calmly, he approaches her and offers his business card… “Peach Puff?” Slowly, Nayeon embarks on a path to discovering her sexuality and everything it can entail.
The story can get depressing and is suited for mature readers only. This is the Manhwa version of Fifty Shades of Grey.

Sign
A few things to know about Cafe Goyo: first, their coffee sucks. Second, never order off the menu. And third, the manager, Yohan, is deaf. So when Soohwa starts as a part-timer, he’s not expected to make good coffee. Instead, he’s expected to learn more sign language beyond “higher,” “pay,” and “please.” But when Yohan offers to give him private lessons, Soohwa is reluctant. Not because he doesn’t want to study but because he has a “hard” time around Yohan. Like, literally. He gets hard. Whenever he hears Yohan’s deep, sexy voice. The webtoon offers many cute characters with lots of fluffy sex. The story is limited, but those that enjoy a little comedy in their smut will enjoy Sign.
This adult webtoon is loaded with sex, and the story does not pick up until the later volumes. The characters lack personality, and there is almost no development. However, those that like saucy sex scenes will love Sign because every update would be a sex scene with no story.

Killing Stalking
Koogi’s dark epic ended in 2019, bringing closure to a story gripped by readers for three intense years. Killing Stalking is a graphic adult webtoon about Yoon Bum, a quiet and intensely skinny boy with a crush on Sangwoo, one of the most popular guys at school. Yoon Bum doesn’t want Sangwoo to know of his profile creeping for fear of being labeled a stalker. His obsession peaks when he breaks into Sangwoo’s home. He goes to the basement, where his dreams of Sangwoo are broken into something darker. And bloody. The webtoon does not offer a positive portrayal of homosexuality. Yoon Bum is seen as an obsessive stalker who spends most of his time trying to break into the home of a man he doesn’t even know loves yet.
This is certainly only for mature readers as it deals with rape, abuse, and Stockholm syndrome. It is the darkest, most disturbing/depressing webtoon and shows how well the author conveyed these emotions through the art and a captivating story.

Love or Hate
Love or Hate is a mature adult webtoon about Haesoo, the cynical writer of a romance column, while Joowon, his former stepbrother, is a famous actor. The two go way back – thrust together when their parents remarried; their relationship is far from simple. Brothers? Friends with benefits? Soulmates? Or nothing at all? Theirs is a delicate balance between lust and loathing, dating and breaking up, irritation and infatuation. When the mysterious photographer “K” takes an interest in Haesoo, events spiral out of control. What direction will this story take as the lines between art and reality become increasingly blurred? Cheap romance? Sensual erotica? Or something much more twisted?
Love or Hate is for those who love a juicy love triangle storyline. The main character is very complex, and the relationships in this are real and hardcore.
