Love in Disguise Webtoon: Original Title & Reading Guide

Written by Huzaifa

Searching for the Love in Disguise webtoon gets confusing before you even reach chapter one. The drama has one English title, the Korean source has another, and articles keep switching between “webtoon” and “web novel.” Are those different stories? Which one should you actually read?

Quick Answer: Love in Disguise is based on the Korean web novel and webtoon 여자인 걸 왜 모르지?, often translated as Why Don’t You Know She’s a Woman? The novel is by Lee A-hyun and Ryu Do-ha; the webtoon credits One Punch Rabbit. Official Korean reading options include KakaoPage and Kakao Webtoon.

This guide covers the source’s identity, its opening premise and how to find the correct edition. There are setup spoilers below, but no killer reveal or ending spoilers.

The original title is your best search shortcut

The Korean title to copy is 여자인 걸 왜 모르지?, romanized as Yeojain Geol Wae Moreuji?

English coverage renders it in several ways, including Why Don’t You Know She’s a Woman? and Why Don’t You Know I’m a Woman? Those variations can make one story look like several separate comics. Match the Korean title and creator names before assuming you have found another adaptation.

The television drama’s Korean title is 나의 유죄인간, commonly translated as My Guilty Human. Love in Disguise is its English title. The series premiered on October 19, 2026, with Yim Si-wan as Yoon Yi-jun and Seol In-ah as Kang Jae-hee.

Here is the detail I had to double-check in the publisher listings: KakaoPage now also displays the source with : 나의 유죄인간 attached to its title. That longer listing connects it to the drama; it does not mean you have stumbled onto a sequel.

Web novel or webtoon? Both, with different credits

The Love in Disguise original story began as prose. The webtoon is its illustrated adaptation, and the television series brings the story to the screen.

I would keep the Korean creator names handy when searching. Official book and comic listings identify 이아현, which corresponds to Lee A-hyun. Some English descriptions use a different spelling, so the original credit is the better reference.

This distinction also answers a practical question: buying a novel volume will not give you illustrated chapters. Likewise, a webtoon episode number is not a chapter reference for the prose edition. Choose the format first, then check the title.

What happens in the original story?

The publisher’s novel description starts with Kang Jae-hee, a former special forces soldier who now serves as a police officer. Her combat experience makes her well suited to dangerous work. Romance is a different problem.

Her assignment puts her close to Yoon Yi-jun, a sheltered third-generation chaebol heir suspected of murder. She must monitor him undercover while working as his personal secretary. The novel’s official blurb specifies a three-month assignment.

Then the operation takes an awkward turn: Yi-jun develops feelings for her.

That is the hook I find more interesting than the rich-boss setup. Jae-hee is there to assess a suspect, while the suspect starts treating their relationship as something personal. Every step toward intimacy makes her job more complicated.

The source is presented as romantic comedy with an investigation running through it. Expect hidden identity, workplace proximity and clashing personalities; do not mistake the murder premise for a promise that every chapter reads like a grim police procedural.

How the undercover setup works, step by step

The opening situation is easier to understand when the investigation and romance are kept separate.

First, there is a murder to investigate. The drama’s official opening-episode description identifies Yi-jun as a suspect in his secretary’s death. Suspicion is the reason for the operation, not proof that he committed the crime.

Second, Jae-hee needs access. Prime Video’s synopsis says company obstruction and insufficient evidence hamper the investigation. A position beside Yi-jun offers a way to observe him closely.

Third, she enters under a false identity. In the television setup, Jae-hee applies as a male secretary. Her employer does not understand who she really is or why she has taken the job.

Fourth, personal attachment complicates the assignment. The original novel’s blurb already establishes his romantic interest. The drama’s premise likewise connects their growing closeness with the search for the truth.

These are the verified opening beats, rather than a claim that the novel, comic and drama stage every introduction in exactly the same order.

Why the disguise matters beyond the comedy

My reading of the premise is that Jae-hee carries two secrets with different emotional consequences. One concerns the identity she presents at work. The other concerns her purpose: she is investigating the person who is becoming attached to her.

Finding out a secretary is a woman answers one question. Finding out that secretary has been gathering information about you raises another: which moments were sincere?

That tension gives the romance something to work through beyond a makeover or an embarrassing misunderstanding. Her professional duty asks her to remain observant and skeptical. Affection could make that harder, even without changing the evidence.

It also gives readers a useful boundary. A romantic moment does not establish Yi-jun’s innocence. Equally, a guarded response does not establish his guilt. Those are interpretations to test against the story, not shortcuts to its solution.

For me, the compelling question is whether trust can survive an introduction built around concealment.

Where to read the Love in Disguise webtoon legally

For the illustrated version, start with the official Kakao Webtoon listing. It displays the Korean title and credits One Punch Rabbit, Lee A-hyun and Ryu Do-ha.

KakaoPage also carries the webtoon. Its series identifier is 60800000, useful for distinguishing it from the novel when search results display nearly identical titles and artwork.

Before starting, check three things:

• Format: 웹툰 means webtoon; 웹소설 means web novel.
• Credits: the comic listing includes 원펀치래빗 alongside the original writers.
• Access: read the current episode’s free, rental or purchase terms before spending money.

The verified listings are Korean editions. An English browser interface or an English search-result title does not mean the chapters themselves have an official English translation.

Any Love in Disguise legal reading guide should make that distinction clear. “Available online” and “available in your preferred language through an authorized publisher” are separate answers.

Where to find the Love in Disguise web novel

The original novel’s KakaoPage listing is separate from the comic. Its series identifier is 54345303, and its authors are Lee A-hyun and Ryu Do-ha.

There is also a Korean ebook edition on Google Play Books under 여자인 걸 왜 모르지? 1, published by Pegasus. The listing offers a sample, which is useful for checking the language and format before purchasing. Store availability and checkout options depend on your region.

Choose prose if your main interest is the written source behind the adaptation. Choose the comic if you want the illustrated telling. Neither requires watching the television version first.

One trap to avoid: a numbered ebook volume and a numbered serialized installment are different units. Volume one is not simply “chapter one” with a different cover. Confirm what the storefront is selling before trying to match your reading progress across editions.

Is an official English translation available?

I could not verify an officially licensed English edition of either the webtoon or novel for this guide.

That is a limit on what can be confirmed, not a claim that an English release can never happen. The reliable reading options identified here are the Korean publisher and retailer listings.

If you come across an English version elsewhere, look for a named publisher, creator credits and a licensing statement. An English title alone does not establish authorization. Nor does a fan recommendation settle the question.

Automatic translation of a page also should not be confused with a publisher’s English edition. It may help with menus, but it does not turn Korean comic panels into professionally translated chapters.

For English-speaking viewers who mainly want to follow the screen adaptation, Prime Video’s official Love in Disguise page lists the series and subtitle options. Check the options shown for your location.

Love in Disguise adaptation differences: what is confirmed?

The clearest visible change is the title: the source’s question becomes Love in Disguise internationally and 나의 유죄인간 on Korean television.

There is also a company-name difference. The original story uses Samgang Group, while the drama introduces Yi-jun’s company as Taegang Group, also romanized as Taekang. That can cause needless confusion when readers move between book discussions and television summaries.

Beyond those details, the shared premise is clear: Jae-hee’s special forces background, Yi-jun’s position as a wealthy suspect and the undercover secretary relationship remain central.

I would be careful with stronger claims. A source synopsis and television publicity are not enough to prove that a supporting character was invented, a reveal moved to a particular episode or the ending was changed.

The same caution applies to “continue reading from chapter X” advice. No reliable episode-to-chapter match has been established here. Start at the beginning if you want to compare the versions without skipping their setup.

Questions readers keep asking

Have you started the novel or webtoon? Tell me which version you chose and what you hope the drama keeps. If you share a theory about Yi-jun’s case, label any source spoilers so other readers can join in safely.
