On September 1, 2026, OTT platform TVING officially announced the casting of Jung Hae In and Shin Sae Kyeong as the main leads for their upcoming original romance drama tentatively titled Love Virus.
The announcement has generated significant buzz across the entertainment industry as it marks the very first time these two acclaimed actors will be sharing the screen together.
Plot Overview and Character Dynamics
Love Virus presents a realistic, contemporary romantic storyline that digs into the nuanced complications of long-term intimacy, identity, and the fear of missing out.
The drama centers on a couple in their ninth year together who were each other’s very first love.
As they naturally approach the topic of marriage, they find themselves questioning whether they are truly ready to commit for life without having ever experienced romantic dynamics with anyone else.
To ensure they enter marriage without lingering doubts, unresolved curiosity, or regrets about missing out on other romantic experiences, the pair decides to make an unexpected choice.
They agree to take a designated “break time” during which they can freely meet and date other people for a set period.
The core narrative follows the emotional transformations, shifts in perspective, and unexpected trials that both individuals navigate as they step away from a familiar nine-year bond and venture into unfamiliar romantic territory.
Jung Hae In stars as Ha Do Woon, a capable lawyer and the long-time boyfriend of Kang Chae Rin.
As the only son of a wealthy family, Ha Do Woon is a character who possesses not only good looks and professional ability but also athletic talent, and he is the type of person who always achieves whatever goal he sets for himself.
For a man accustomed to predictability, structure, and success, navigating an intentional romantic separation forces him to face emotional variables he cannot simply control or organize.
Shin Sae Kyeong takes on the role of Kang Chae Rin, a dentist who has been dating Ha Do Woon for nine years.
She has been in the spotlight for her stunning looks since her school days and has lived a life that lacks nothing in terms of career, romance, and work-life balance.
However, despite her enviable lifestyle, she has recently begun to feel skeptical about her life, which has followed only one path thus far.
Taking a break from her long-term relationship becomes her way of confronting that internal skepticism and testing whether her current life is truly what she desires.
Production Expectations and Broadcast Timeline
The collaboration between Jung Hae In and Shin Sae Kyeong is drawing strong expectations due to their proven capabilities in the romance and drama genres.
Jung Hae In has built a solid career portraying deeply relatable, emotionally grounded figures in both romantic and dramatic projects.
Shin Sae Kyeong has similarly established a reputation for bringing poise, depth, and charm to diverse roles across modern and historical dramas.
By taking on characters who have known each other for nearly a decade, both actors are expected to deliver a mature depiction of comfort, vulnerability, and the friction that arises when long-standing routines are suddenly broken.
Rather than relying on traditional romantic meeting tropes, Love Virus focuses heavily on the psychological reality of modern relationships- exploring whether a long-term foundation can survive the test of romantic freedom and personal rediscovery.
According to TVING, the production team is actively preparing for filming. “Love Virus,” which marks Jung Hae In and Shin Sae Kyeong’s first project together, is slated to premiere in 2027.
Fans can expect further announcements regarding secondary casting, director details, and specific release schedules as production moves forward over the coming year.
