On March 19, Ayane uploaded a video to her social media platform accompanied by a caption that humorously yet touchingly noted the personality differences within their household: “An extremely, extremely F child born to a T mom and dad.” This reference to the Myers-Briggs Type Indicator (MBTI), where ‘F’ stands for Feeling and ‘T’ for Thinking, underscored the high level of emotional intelligence displayed by their daughter in response to seeing her mother prepare for a medical procedure.
A Viral Moment of Empathy and Innocence
The footage captures a private yet universal moment in the lives of couples undergoing fertility treatments. In the video, Ayane is seen preparing to administer a self-injection, a standard but often painful part of the IVF protocol. Ru Hee, witnessing the sight of the syringe, immediately exhibits signs of distress. Her reaction was not one of simple curiosity but of profound concern for her mother’s well-being.
As Ayane handled the medical equipment, Ru Hee’s expression shifted to one of sadness. The toddler attempted to intervene physically, reaching out to take the syringe away while repeatedly pleading, “Don’t do it.” The scene escalated in emotional intensity when Ayane attempted to lift her clothing to expose the injection site on her abdomen. In a protective gesture, Ru Hee stood on her tiptoes and used her small hands to pull the fabric back down, effectively trying to shield her mother from the perceived harm of the needle.
Lee Ji Hoon, observing the interaction, attempted to comfort the child by explaining that the procedure was necessary and would not cause significant pain, stating, “Mom, it’s not going to hurt.” However, Ru Hee remained unconvinced, eventually lying down on the floor in tears. The display of empathy eventually led Ayane to pause the procedure, comforting her daughter by saying, “Mom won’t do it. Thank you for worrying.” Despite the assurance, the video showed Ru Hee maintaining a vigilant watch over her mother, ensuring that the “threat” of the injection did not return.

The Biographical Context of Lee Ji Hoon and Ayane
The public interest in this moment is rooted in the high-profile nature of the couple and their unconventional but celebrated romance. Lee Ji Hoon, a mainstay in the South Korean entertainment industry since the late 1990s, transitioned from a successful "ballad prince" singing career to becoming a respected actor in both television dramas and musical theater. His marriage to Ayane, a Japanese national who is 14 years his junior, captured public attention when it was first announced in 2021.
The couple’s relationship has been characterized by a high degree of public engagement, particularly through their appearance on the popular reality program Same Bed, Different Dreams 2 – You Are My Destiny. On the show, they showcased their daily lives, including the challenges of navigating a multi-generational household—as they live in a building with Lee’s extended family—and their shared goal of starting a family.
Their first child, Ru Hee, was born following a successful IVF cycle, a journey they also shared with the public. The birth of their daughter was seen as a triumphant milestone, yet the couple has remained vocal about their desire for a second child, a path that has proven to be fraught with emotional and physical challenges.
The Reality of Secondary Infertility and IVF Challenges
The recent video is more than a "cute" family moment; it serves as a window into the reality of secondary infertility and the rigors of the IVF process. Secondary infertility—the inability to conceive or carry a pregnancy to term after previously giving birth—is a growing concern globally. For Lee Ji Hoon and Ayane, the journey toward a second child has been marked by heartbreak.
Last year, the couple revealed that they had suffered the loss of a second pregnancy. Ayane has been candid about the psychological impact of miscarriages, sharing the grief that accompanies such a loss while simultaneously maintaining the resolve to try again. The decision to undergo IVF once more involves a grueling regimen of hormonal medications, frequent clinic visits, and the physical discomfort of self-administered injections, which are designed to stimulate egg production or prepare the uterine lining.

The physical nature of these treatments often makes it impossible to hide the process from young children in the household. As seen in the viral video, children are often highly sensitive to changes in their parents’ demeanor or the presence of medical apparatus, leading to moments of confusion or protective anxiety.
Cultural Implications of the "T vs. F" Dynamic
Ayane’s use of the MBTI terminology in her caption reflects a significant cultural trend in South Korea. The MBTI has become a ubiquitous shorthand for personality traits in Korean society, often used in dating, workplace environments, and parenting discussions. By labeling herself and Lee Ji Hoon as "T" (Thinking) types and Ru Hee as an "F" (Feeling) type, Ayane was highlighting the contrast between the parents’ pragmatic approach to the medical necessity of IVF and the daughter’s purely emotional, empathetic response.
In the context of South Korean parenting discourse, an "F" child is often described as being highly attuned to the emotions of others, requiring a gentler communication style. The video served as a practical demonstration of these personality archetypes, showing how a child’s emotional logic can sometimes override a parent’s rational planning, necessitating a pause in the "Thinking" process to address the "Feeling" needs of the family unit.
Broader Impact and the Stigma of Fertility Treatments
The transparency of celebrities like Lee Ji Hoon and Ayane regarding their fertility struggles plays a crucial role in destigmatizing IVF and miscarriage in South Korea. Historically, fertility issues were often treated as private burdens, sometimes carrying a sense of shame or social stigma. By sharing the "unfiltered" moments of their journey—including the tears of their child and the sight of syringes—the couple contributes to a more open dialogue about the realities of modern family planning.
This openness is particularly relevant in the context of South Korea’s current demographic crisis. The country consistently reports the lowest total fertility rate in the world, leading the government to implement various subsidies and support programs for fertility treatments. As more couples marry later in life, the reliance on medical intervention to conceive has increased. Public figures who humanize this process help others feel less isolated in their own struggles.

Psychological Analysis of the Child’s Reaction
Child development experts often note that toddlers and young children are "emotional sponges." Ru Hee’s reaction to the syringe is a textbook example of a child’s protective instinct. At her age, the concept of "medicine to help have a sibling" is too abstract to grasp; instead, she perceives a sharp object and her mother’s potential pain.
The way Ayane and Lee Ji Hoon handled the situation—by acknowledging Ru Hee’s feelings rather than dismissing them—is cited by many viewers as a positive example of responsive parenting. By choosing to "give up" on the injection at that specific moment to comfort their daughter, they prioritized the child’s immediate emotional security, which is vital for maintaining trust during a period where the mother’s body is undergoing significant changes due to hormonal treatments.

Implications for the Future
As Lee Ji Hoon and Ayane continue their path toward a second pregnancy, their story remains a significant narrative in the landscape of South Korean celebrity culture. It shifts the focus from the glamour of the entertainment industry to the universal human experiences of hope, loss, and the complexities of raising a child while pursuing medical solutions for infertility.
The overwhelming support from the public following the video’s release suggests a growing appetite for authentic portrayals of family life. Viewers have left thousands of comments praising Ru Hee’s "filial piety" and "pure heart," while also offering words of encouragement to Ayane as she navigates the physical demands of her second IVF journey.

In conclusion, the simple act of a daughter trying to protect her mother from a needle has opened up a broader conversation about the emotional labor of IVF. It underscores that while the medical process is technical and "Thinking" oriented, the experience for the family is profoundly "Feeling." For Lee Ji Hoon and Ayane, the road to expanding their family is paved with both medical challenges and the heartwarming, if sometimes obstructive, empathy of their firstborn. As they move forward, the couple continues to serve as a prominent voice for those navigating the difficult but hopeful waters of assisted reproduction.
