Popular Korean actors Song JiHyo and Kim ByungChul recently appeared as guests on a popular YouTube talk show, sparking conversations about their fantastic on-screen “couple chemistry.” In a video uploaded on November 3, 2025, to the “Brave Bros Shin DongYup” channel, the two stars shared amusing anecdotes about how they address each other, much to the surprise of hosts Shin DongYup and Jung HoChul.
The Story Behind the “Yeobo” Nickname
The main topic of discussion revolved around the term “yeobo,” a Korean word typically used between married couples. Host Shin DongYup noted the palpable “married couple chemistry” between the two actors, which led to Song JiHyo’s surprising revelation about their on-set dynamic.
Song JiHyo’s Practical Reason
Song JiHyo explained that for their acting roles, she needed a term of endearment for Kim ByungChul. She found common options like “jagiya” (darling) or “oppa” (a term used by females for older males) to feel awkward in the context of their characters. As a solution, she decided to call him “yeobo,” which she felt fit their on-screen relationship perfectly. This choice highlights the professionalism these Korean actors bring to their roles to build believable chemistry.
Hosts Express Their Surprise
The hosts, Shin DongYup and Jung HoChul, were taken aback by her choice. They confessed that despite being married or in a long-term relationship, neither of them had ever used the term “yeobo” with their own partners. Their reaction underscored how unique Song JiHyo’s approach was, even for native Koreans, and how it contributed to the convincing couple chemistry with Kim ByungChul.
A Deeper Look at Song JiHyo’s Discomfort with “Oppa”
The conversation on the YouTube talk show also shed light on a personal quirk of the beloved actress. Song JiHyo admitted she has always found it difficult to use the word “oppa,” a very common term in Korean culture for an older brother or male friend.
The Two-Year Wait on “Running Man”
To illustrate her point, Song JiHyo shared a fascinating story from her time on the long-running variety show “Running Man.” She revealed that it took her two full years to become comfortable enough to call her older male castmates “oppa.” This anecdote provides fans with a deeper understanding of her personality and why she opts for more distinct terms of endearment. Her candidness on the “Brave Bros Shin DongYup” show offered a rare and entertaining glimpse behind the scenes.
