K-ritual: How Korea rewrote Valentine’s Day

Jason Lim

Last weekend, my wife and I went shopping at Costco, a timeless weekend ritual. There, we saw rows of vases with flowers and realized that another ritual, Valentine’s Day, was imminently upon us.

Every Feb. 14, people around the world participate in a ritual that feels timeless. Roses are purchased by the millions. Chocolates are carefully selected. Restaurants fill. In Korea, women give chocolates on Valentine’s Day, and one month later men reciprocate on White Day. To many, this feels natural, inevitable — as if romance itself demands such gestures.

But Valentine’s Day (much like Christmas) is an evolving story — a tapestry woven from pagan rites, religious adaptation, medieval poetry, industrial marketing and modern consumer culture. Its evolution and endurance tell us something profound about human beings: We are the only animals whose belief in shared stories can shape reality that often transcends even our biology.

A quick search will tell you that the origins of Valentine's Day lie far from heart-shaped boxes. In ancient Rome, mid-February was marked by Lupercalia, a fertility festival that included ritual sacrifice and symbolic pairings intended to bless unions. When Christianity spread, it often absorbed rather than erased existing customs. By the late fifth century, Pope Gelasius I designated Feb. 14 as the feast day of St. Valentine, a martyred priest whose legend gradually became associated with romantic devotion rather than sacrifice.

Centuries later, poets such as Geoffrey Chaucer linked mid-February with birds choosing their mates, reinforcing the romantic association. By the 18th and 19th centuries, handwritten love notes became fashionable in Europe. The Industrial Revolution then transformed private sentiment into mass production: printed cards, boxed chocolates, roses shipped across continents. What began as fertility rites and martyrdom evolved into confectionery and candlelight dinners.

This pattern — the layering of meanings across time — reveals how traditions rarely begin where we think they do. They accumulate, adapt and are reinterpreted. And perhaps no modern example illustrates the power of narrative better than the diamond engagement ring.

Before the late 19th century, diamond engagement rings were not a universal custom. Diamonds were rare but not yet the unquestioned symbol of eternal love. Then came De Beers. In the early 20th century, facing fluctuating demand and growing supply, the company orchestrated one of the most successful marketing campaigns in history. Through strategic control of supply and carefully crafted messaging — most famously the slogan “A diamond is forever” — De Beers embedded the idea that a diamond ring was not merely a gift but a necessary expression of commitment.

Hollywood reinforced the message. Social norms followed. Within a few decades, a tradition had solidified so completely that it felt ancient. Scarcity was engineered. Meaning was manufactured. And yet, once absorbed into the cultural imagination, the diamond ring ceased to feel like marketing. It became ritual.

Humans alone possess this extraordinary capacity to manufacture a shared belief. Our species can believe in myths, religions, national borders, currencies or holidays — and those beliefs shape behavior more forcefully than immediate survival needs. People will sacrifice comfort, wealth and sometimes even safety for the sake of narrative identity. Rituals reinforce belonging. They affirm that we are part of a shared emotional script.

Korea offers a particularly fascinating chapter in this evolving narrative. Rather than simply importing the Western version of Valentine’s Day, Korea reshaped it. On Feb. 14, women give chocolates. One month later, on March 14, men respond on White Day with gifts of their own. And in another cultural twist, April 14’s Black Day gives singles a communal moment to gather and eat jajangmyeon (black bean noodles) in mutual commiseration of the giftless ones. I have to admit, Black Day is my favorite day of the series because it’s so genius.

These layered days were not decreed by ancient tradition. They emerged through a combination of commercial creativity and social adaptation. But over time, they have become normalized, expected even meaningful. Korea did not merely adopt Valentine’s Day; it expanded the storyline. K-ritual, perhaps?

Korea transformed a single romantic holiday into a sequence of relational rituals. The narrative grew more complex. It became reciprocal. It reflected local social dynamics while remaining connected to global tradition. Valentine’s Day, then, is less about romance itself and more about the remarkable human ability to construct and inhabit shared fictions. These fictions are not false in the trivial sense; they are socially real. A diamond’s value exists because we agree it does. A holiday’s meaning exists because we participate in it.

Love, like tradition, is sustained by belief. We tell stories about what it means, we embed those stories in rituals, and we pass them on. Over centuries, Lupercalia became St. Valentine’s feast. That feast became poetry. Poetry became candy hearts. Marketing became diamond rings. And in Korea, Valentine’s Day became White Day, then Black Day — a further evolution in a long chain of reinterpretations.

The story continues because we continue to believe it. Like love.
