Shin Ye Eun Joins Park Bo Gum in Talks for Time-Slip Romance Night Traveler

Park Bo Gum (박보검) and Shin Ye Eun (신예은) are both in talks to lead "Night Traveler," a time-slip romance drama written by Yoon Ji Ryeon, the screenwriter behind Boys Over Flowers and Move to Heaven, according to an exclusive report by SPOTV News on April 2, 2026. The project, which has been in development since mid-2025, would pair two of Korea's most in-demand actors for a story spanning 1937 and the present day. Park Bo Gum's agency THE BLACK LABEL confirmed he is reviewing the offer, while Shin Ye Eun's agency npio Entertainment told Ilgan Sports that the project "is one of the offers she received and is currently reviewing." Neither casting has been finalized, but if both sign on, production is expected to move forward immediately. The project has been in active development since Park Bo Gum was first linked to it in May 2025.

What Is Night Traveler About?

Night Traveler follows a lawyer and a forensic investigator who are separated by nearly a century but connected through the same apartment. Set across two timelines, 1937 and the present day, the two leads meet during brief windows at night when the boundaries between their eras collapse. As these encounters continue, they uncover secrets that link their lives across decades. The premise blends period drama with modern thriller elements, anchored by a romance that operates across time itself. Yoon Ji Ryeon's involvement adds significant weight to the project, as confirmed by multiple Korean media outlets including Soompi. The writer's track record suggests Night Traveler will lean into emotional character work rather than relying on the time-slip gimmick alone. No director has been publicly announced, and the broadcast network or streaming platform has not been confirmed.

Why Park Bo Gum Is the Perfect Fit

Park Bo Gum built his reputation as Korea's go-to romantic lead through Love in the Moonlight (2016) and Encounter (2018), then proved his range with Record of Youth (2020) before enlisting for military service in August 2020. He completed his service in February 2022 and signed with THE BLACK LABEL in January 2023 after a decade at Blossom Entertainment. His return to the screen has been nothing short of dominant. Netflix's When Life Gives You Tangerines, which premiered in March 2025, became one of the platform's highest-rated Korean originals. K-drama review site The Fangirl Verdict called it "a masterpiece" and praised Park's performance alongside IU as award-worthy. He followed that with the action comedy Good Boy and has been hosting The Seasons: Park Bo Gum's Cantabile. Night Traveler would mark his return to the pure romance genre, a space where he's proven he can deliver massive ratings and genuine emotional depth.

Shin Ye Eun's Rise to Leading Lady Status

Shin Ye Eun first gained national attention through the web series A-Teen (2018), which earned her the nickname "Nation's First Love" for her portrayal of Do Hana. But her trajectory since then has been anything but predictable. She delivered a breakout dramatic turn in Netflix's The Glory (2022-2023), playing the younger version of Park Yeon Jin, one of the drama's most chilling antagonists. That role, as reported by the Chosun Ilbo, completely transformed public perception of her range as an actress. She then pivoted to historical territory with Jeongnyeon: The Star Is Born (2024), a drama centered on women's traditional theater where she performed pansori and choreography on screen. In a post-production interview, she revealed she practiced vocal techniques "for nearly a year" to prepare for the role.

Shin is currently set to appear alongside Lee Jae Wook in the ENA romantic comedy Doctor on the Edge, and she was previously in talks for Studio Dragon's High School Queen. If Night Traveler goes forward, it would be her most high-profile leading role to date, paired with one of the biggest names in Korean entertainment.

Yoon Ji Ryeon: The Writer Who Changed K-Drama Romance

The screenwriter behind Night Traveler has shaped some of the most defining moments in Korean television. Yoon Ji Ryeon wrote Boys Over Flowers (2009), the drama that turned the Hallyu Wave into a global phenomenon and launched the careers of Lee Min Ho and the original F4 cast. She followed that with Angel Eyes (2014) and Operation Proposal (2012), both commercial successes that cemented her status in the romance genre. Then she shifted gears entirely with Move to Heaven (2021), a critically acclaimed Netflix series about a trauma cleaner with Asperger syndrome that earned widespread praise for its emotional sensitivity. That genre pivot is exactly what makes Night Traveler intriguing. Yoon has proved she can write crowd-pleasing romance and deeply human character drama. A time-slip narrative that demands both feels tailor-made for her strengths.

What This Means for the K-Drama Landscape

If both actors confirm their involvement, Night Traveler would join a growing wave of high-concept romance dramas betting on established star power paired with ambitious premises. The time-slip subgenre has produced some of K-drama's most beloved titles, from Signal (2016) to Lovely Runner (2024), and audiences have shown an appetite for stories that layer genre mechanics on top of genuine emotional stakes. We've been tracking both actors' post-2024 trajectories closely, and this pairing makes strategic sense. Park Bo Gum brings the proven audience and the romantic lead credibility. Shin Ye Eun brings the dramatic range and the critical respect. Put Yoon Ji Ryeon's writing behind them, and you have the ingredients for one of 2026's most anticipated projects. Whether the casting negotiations close successfully remains to be seen, but the early buzz is already building fast.
