Jungjin (정진)

As a longtime member of Shinhwa, one of South Korea's most enduring male groups, Jun Jin has spent nearly three decades at the center of an act that has outlasted almost every contemporary from its 1998 debut era. Born Park Jung Jin on May 1, 1987, he has functioned as both a performing member of Shinhwa and, in more recent years, a familiar face in Korean lifestyle media alongside his wife, influencer Ryu Yi-seo.

A career built on longevity

Shinhwa marked its 28th debut anniversary in March 2026, a milestone Jun Jin acknowledged publicly by describing his fellow members as "brothers and friends" — a statement that carried particular weight given that it came while member Kim Dong-wan was navigating an ongoing public controversy. The comment was characteristic of Jun Jin's long-held positioning within the group: steady, loyal, and outwardly committed to collective identity over individual prominence.

Jun Jin also held membership in A'ST1, though the material available does not detail the nature or timeline of that affiliation in full.

Life beyond the stage

In recent years, Jun Jin's public profile has been shaped as much by his marriage and domestic life as by his music career. He and Ryu Yi-seo, who documents their life together on her YouTube channel, have shared candid moments across multiple platforms — from a mildly chaotic Jeju Island visit to his mother's home in May 2026, during which the couple discovered they had no idea she had moved, to a lighter anecdote about a disagreement during an unplanned honeymoon trip to Daejeon.

The couple's journey toward a second child has also been part of their public narrative in 2026. Ryu Yi-seo began IVF treatment in the spring of that year, sharing updates on her YouTube channel — including the physical demands of egg retrieval injections and the emotional texture of the process. Jun Jin, appearing on the couple's joint content, expressed regret at being unable to ease her discomfort. The openness with which both have approached the subject has drawn a steady following to their shared content.
