Who Is Lee Kiyoung's Wife? Exploring Relationships In Regressor Instruction Manual

Ally Tillman 08 Jun 2025

The captivating world of web novels and webtoons frequently presents us with compelling characters grappling with extraordinary circumstances. Among the stories that have captivated readers, “Regressor Instruction Manual” (회귀자 사용설명서), also known as “How to Use a Returner,” stands out. This tale centers on Lee Kiyoung, a man granted the ability to rewind time, to regress and change the future. As readers delve into his complex journey of survival and manipulation, a common question arises: who is Lee Kiyoung's wife? While the narrative is rich with intricate plots and character development, the answer to Lee Kiyoung's marital status, particularly concerning a defined spouse, is more nuanced than one might expect. This article will explore the characters surrounding Lee Kiyoung, focusing on the most prominent female figure in his life and the nature of their bond, based on available information.

Lee Kiyoung: A Master of Manipulation and Survival

At the heart of “Regressor Instruction Manual” is Lee Kiyoung (이기영), the main character whose actions drive the intricate plot. Kiyoung is not your typical heroic protagonist. His approach to survival in a dangerous new world is marked by cunning, calculation, and a willingness to use others for his own benefit. To understand his relationships, one must first understand Kiyoung himself.

Appearance and Persona

Lee Kiyoung's appearance is often described as unremarkable, even meek, which serves as an excellent disguise for his true nature. Despite this initial impression, he is undeniably handsome. He possesses features that can subtly shift between charmingly innocuous and unsettlingly cunning, reflecting his dualistic personality. Of average height and build, he lacks the imposing physical presence often associated with powerful protagonists, further emphasizing that his strength lies in his mind, not his brawn.

His Cunning Mind and Abilities

Kiyoung's primary asset is his intelligence and his unique ability to regress, allowing him to rewind time and alter outcomes. Once he found himself in the other world, Lee Kiyoung observes people around him through his mind's eye, constantly strategizing to improve his chances of survival. He allied with Park Deokgu early on, a calculated move to secure a loyal companion. His plans are often meticulously crafted, sometimes with devastating consequences for those who stand in his way or become collateral damage. He is a master of psychological manipulation, using his unassuming demeanor to disarm others while secretly orchestrating events to his advantage.

The Dark Past of a Regressor

Perhaps one of the most shocking revelations about Lee Kiyoung, often a major spoiler for new readers, is his role in the first regression. In that timeline, Kiyoung was the main antagonist who killed the regressor and destroyed the world. This dark past looms over his current actions, raising questions about whether his present path is truly different or merely a more refined version of his manipulative tendencies. The narrative suggests that the future Kiyoung might take a different path this time, especially since he has met Hyunsung and others, implying a potential for change, however slight.

Jung Hayan: The Devoted, Yet Terrifying, Companion

When discussing Lee Kiyoung's romantic interests or potential "wife," one name consistently comes to the forefront: Jung Hayan. She is arguably the most significant female character directly linked to Kiyoung in a deeply personal and often unsettling way. Their relationship is one of the most intriguing and complex dynamics in the novel.

Her Distinctive Appearance and Personality

Jung Hayan is described as a brunette with short brown hair in a bob cut and brown eyes. She has sharp and beautiful features and a mature body. Interestingly, while her body can pass as mature, the only reason Kiyoung knew of her real age being 30 was because of his ability; everyone else still thinks she is in her twenties. Her personality can be described as scummy yet fiercely loyal. Her loyalty cannot be easily gained, yet once you get it, it is absolute and unwavering, especially towards Lee Kiyoung.

The Depth of Her Loyalty (and Obsession)

Lee Kiyoung's encounter with Jung Hayan was a calculated move. After escaping a dangerous room with Park Deokgu, they struggled to kill monsters, and Kiyoung ended up "saving" Jung Hayan after confirming her potential. This act cemented her profound devotion to him. This devotion, however, quickly veers into obsessive territory. Park Deokgu's girlfriend even told Kiyoung about Hayan’s scary stalking ability, highlighting the extreme nature of her attachment.

Hayan's possessiveness is a recurring theme. For instance, when new members were being selected (a girl indicated by Lee Jihye and Jung Hayan indicated by Lee Kiyoung), Hayan's jealousy was unleashed. Kiyoung's plan to integrate new members was too effective, causing Jung Hayan to attack the other girl with magic, severing her four limbs and making her unable to talk due to a barrier. This incident vividly demonstrates the dangerous lengths to which Hayan will go to protect her bond with Kiyoung, or perhaps to eliminate any perceived rivals for his attention.

Hayan's Powers and Their Dangerous Edge

Hayan possesses formidable magical abilities, making her a powerful asset in Kiyoung's schemes. However, her emotional instability and extreme loyalty to Kiyoung mean that her powers can be incredibly destructive when her possessiveness is triggered. Her actions are often driven by her desire for Lee Kiyoung, even to the point of causing immense harm to others.

Unraveling the "Wife" Question: The Nature of Their Bond

Given Jung Hayan's intense devotion and central role in Lee Kiyoung's life, many readers speculate about her status as his romantic partner or even his wife. However, based on the provided data, there is no explicit mention of Lee Kiyoung being married or Jung Hayan being formally designated as his wife.

A Calculated Alliance, or Something More?

Kiyoung's relationship with Hayan is complex. While he undoubtedly benefits from her immense power and unwavering loyalty, his initial approach to her was a calculated move to secure an asset. He manipulates her emotions, leveraging her devotion to achieve his goals. Whether his feelings for her transcend mere utility into genuine affection or love is a subject of ongoing discussion among fans. Hayan's desire for Kiyoung is clear, as indicated by phrases like "1st world because she wanted Lee Kiyoung to." However, the narrative focuses more on the strategic and often dark aspects of their dynamic rather than a conventional romance.

The Absence of a Defined Spouse

The provided information, which includes details about other characters' marriages (like a couple who married in 2015 and has an adopted daughter named Sophia, or the wedding of Ki Hong Lee), explicitly does not link any such marital status to Lee Kiyoung. This suggests that, within the scope of the given data, Lee Kiyoung's journey is primarily focused on survival, power, and manipulation, with romantic relationships taking a backseat or being portrayed in a non-traditional, often unsettling, manner through characters like Jung Hayan.

Other Relationships and the Broader Narrative

It's important to note that the provided data also touches upon other relationships and individuals that are distinct from Lee Kiyoung's narrative. For instance, there's mention of an actress named Hayoung who appeared in short movies and has a boyfriend, and details about the actor Ki Hong Lee, including his birth, relocation, education, and an intimate wedding ceremony attended by family and close friends like Britt Robertson, O’Brien, and Arden Cho. These details are about real-world individuals or separate fictional contexts and should not be conflated with Lee Kiyoung's story from "Regressor Instruction Manual." The focus of Lee Kiyoung's story remains his cunning strategies, his past as an antagonist, and his complex interactions with characters like Jung Hayan and Park Deokgu.

Conclusion: An Open-Ended Romance in a Dangerous World

In summary, while readers of "Regressor Instruction Manual" are often curious about Lee Kiyoung's romantic life and whether he has a wife, the provided data does not explicitly state that he is married. Instead, the narrative highlights his profoundly complex and often manipulative relationship with Jung Hayan. Hayan's intense loyalty, bordering on obsession, and her formidable powers make her the most significant female figure in Kiyoung's journey. Their bond is characterized by Kiyoung's calculated use of her devotion and Hayan's dangerous possessiveness, rather than a conventional romantic partnership. As Lee Kiyoung navigates a world filled with extraordinary circumstances and grapples with his own dark past, his personal relationships remain as enigmatic and strategic as his very existence.
