1. Why is Cha Eunwoo's younger brother such a hot topic?

The initial attention was drawn to Cha Eunwoo when his social media accounts were temporarily made public and photos of a man who bore a striking resemblance to him were spread. The resemblance, with his large eyes, well-defined facial lines, and well-proportioned physique, was so great that it was called a "genetic victory," and people began talking about it. However, he is not a celebrity, but an ordinary person, and his social media accounts were quickly made private to avoid excessive attention. This led to widespread discussion that "family privacy should be protected."

4. The truth behind the once-widely-circulated "showbiz debut rumor"

After the photos were leaked, unfounded rumors spread that he was "active as a trainee" and "preparing to become an advertising model," but these were not true. Furthermore, the theory that he was a "global intern at Cheil Worldwide," which was also circulated by some, was simply speculation with no official confirmation. The important thing to note is that Lee Dong-hwi is someone who has built his career not in the entertainment industry, but in the fields of AI and brand data analysis.

5. 2025 Status: Appearing as an official speaker at the AI Summit

In November 2025, his name and photo were published as an official speaker at the "AI Summit Seoul & Expo 2025," which caused quite a stir.

The session was titled "AI Recipe: How the AI I Made for My Brother Evolved into a Brand Verification Tool."

He started out by personally creating an AI data collection model to analyze his brother Cha Eunwoo's image and monitor fan community reactions, but has since expanded into corporate solutions for brand evaluation and flame risk management.
