Yi Kwang-su's The Heartless (Mujeong), first serialized in the Maeil sinbo in 1917, is widely considered the first modern Korean novel. It arrived at a critical juncture in Korean history, during the early years of the Japanese colonial period—a time when the nation was struggling to reconcile its deep Confucian heritage with the overwhelming tide of Western modernity and enlightenment.

The novel follows Lee Hyong-sik, a young teacher of English, as he navigates a complex web of relationships and ideological shifts. Through his eyes, we witness the erosion of traditional marriage customs, the rise of modern education, and the growing self-awareness of the Korean intellectual class.

To have a heart is to suffer the weight of a nation’s transition.

The Heartless, 1917

The Tension of Enlightenment

At its core, The Heartless is an "enlightenment novel" (gyemong soseol). It is a text about education—not just in the sense of schooling, but as a broader project of national and personal awakening. Hyong-sik embodies this drive for knowledge, yet he is constantly pulled back by the "heartless" realities of his society: the rigid social hierarchies and the emotional detachment of those still clinging to the old ways.

The title itself, Mujeong, meaning "heartless" or "emotionless," refers to this perceived lack of modern sentiment (jeong) in traditional Korean society. Yi Kwang-su uses the novel to advocate for a new kind of "heart"—one informed by modern education, individual freedom, and national consciousness.

The Triangulation of Desire

The narrative is driven by a romantic triangle involving Hyong-sik, the traditional and virtuous Yeong-chae, and the modern, educated Seon-hyeong. This triangle serves as a brilliant allegory for the choices facing Korea at the time:

Yeong-chae represents the "old" Korea—haunted by the past, bound by filial piety, and ultimately tragic in her inability to adapt.
Seon-hyeong represents the "new" Korea—intellectual, Christian, and forward-looking, yet often detached from the deeper emotional roots of the culture.
Hyong-sik stands between them, oscillating between pity for the old and attraction to the new.

A New Prose for a New Nation

Beyond its thematic importance, The Heartless revolutionized the Korean language. Yi Kwang-su broke away from the dense, classical hanmun styles of the past, adopting a more colloquial and accessible prose. He successfully integrated Western psychological realism into the Korean narrative, allowing readers to explore the inner lives of characters with unprecedented depth.

"The sound of the steam engine was the heartbeat of a world Hyong-sik had only read about in books, now screaming at the gates of Seoul."

A Controversial Legacy

While The Heartless was a massive success upon its release, its legacy is inextricably linked to Yi Kwang-su's later life. His eventual collaboration with the Japanese colonial government has cast a long shadow over his literary achievements. In contemporary Korea, he is often viewed through a dual lens: as a literary pioneer who "invented" the modern novel, and as a national traitor (chinilpa).

However, within the context of 1917, The Heartless was a revolutionary act. It provided a roadmap for the modern Korean self and established the linguistic foundation upon which all subsequent Korean literature would be built. To understand the Korean modern experience, one must start with the heartless world of Yi Kwang-su.
