On April 10, actress Lee Si Young uploaded a short video to her Instagram story showing her children welcoming her son home from school. The clip, meant to capture a sweet, everyday moment of parenting, quickly caught fans’ attention for an entirely different reason: a mysterious man standing behind his son, holding his school bag.
In the video, Lee Si Young’s young daughter is seen being held by what appears to be the actress as the family waits at the open gate for their eldest son to return home.
As his son headed towards the house, onlookers noticed an unidentified man following him, carrying a backpack and appearing to help him with the child’s belongings.
The actress captioned the video: “When Oppa finishes school, I always leave the door open and wait like this.”
While Lee Si Young offered no explanation as to the man’s identity, his presence immediately fueled curiosity among fans and online communities.
As the man was shown casually helping his son’s school pick-up, many netizens began to speculate whether it could be:
- A family acquaintance
- A relative or close friend
- A childcare assistant or household help
So far Lee Si Young has not commented publicly on the man’s identity.
Lee Si Young married a non-famous restaurateur in 2017, but the couple divorced early last year after eight years of marriage.

In July last year she revealed she was pregnant, explaining that she had been preparing to have a second child through IVF treatment during her marriage.
After the divorce, as the deadline for embryo storage approached, Lee Si Young made a personal decision to proceed with embryo implantation on her own.
She gave birth to her daughter in November and is now raising both her son and daughter as a mother of two.
Despite the online curiosity, many fans praised Lee Si Young for continuing to share honest glimpses of her motherhood journey while maintaining privacy about her personal relationships.
