Our Universe Premieres on tvN With Promising Ratings

tvN's newest romantic comedy Our Universe officially premiered on February 4, 2026, stepping into the Wednesday-Thursday primetime slot as the only drama airing in that timeslot. The series, which stars Bae In Hyuk, Roh Jeong Eui, and Park Seo Ham, recorded a nationwide viewership rating of 1.9 percent for its debut episode according to Nielsen Korea, a steady start for a mid-week romance offering.

Airing every Wednesday and Thursday at 10:40 PM KST on tvN, the drama benefits from having no direct competition in its timeslot, giving it a unique opportunity to build its audience steadily over the coming weeks. The series is also available internationally on Viki with English subtitles, opening it up to the global K-drama fanbase from day one.

A Story of Unexpected Family

Our Universe tells the story of two twenty-eight-year-old in-laws, Seon Tae Hyeong (Bae In Hyuk) and Woo Hyun Jin (Roh Jeong Eui), whose lives are turned upside down when they are suddenly tasked with raising their infant nephew, Woo Joo, following the unexpected passing of the child's parents. Despite starting off on bad terms and having no prior close relationship, the two are forced to live under the same roof to care for the 20-month-old baby.

What begins as an awkward and tension-filled cohabitation gradually evolves into something deeper as both characters learn to navigate parenthood, grief, and their growing feelings for each other. The drama blends comedic moments with emotional depth, creating a warm and relatable narrative about found family and the unexpected ways love can enter our lives.

Domestic and International Performance

Following its 1.9 percent premiere, the drama's domestic ratings have stabilized in the 1.3 to 1.5 percent range, typical for a mid-week cable drama without direct timeslot competition. By its fourth episode on February 12, the drama earned a 1.5 percent average nationwide rating, its strongest Thursday performance at that point.

Where Our Universe has truly excelled is on the international stage. The series has claimed the number one position on streaming charts in 142 countries and regions, including the United States, Brazil, France, India, and the United Arab Emirates, demonstrating the global appetite for its heartwarming premise. Industry observers note that tvN's Wednesday-Thursday slot has historically been a launching pad for breakout hits, and the drama's strong international performance suggests significant word-of-mouth potential.

Cast Spotlight

Bae In Hyuk, known for his roles in My Roommate Is a Gumiho and Cheer Up, takes on his most emotionally layered role yet as a young man suddenly thrust into fatherhood. Roh Jeong Eui, who impressed audiences in Alchemy of Souls and The Midnight Romance in Hagwon, brings both strength and vulnerability to her character. Park Seo Ham rounds out the main cast, adding another dimension to the household dynamic.

With its heartwarming premise, strong casting, and impressive international reception, Our Universe is positioning itself as a feel-good highlight of the early 2026 drama season. New episodes air every Wednesday and Thursday at 10:40 PM KST on tvN.
