Cha Eun Woo’s younger brother, Lee Dong Hwi, has drawn public attention after appearing as a speaker at a major AI conference.
On November 10, Lee took the stage at the 'AI Summit Seoul & Expo 2025' held at COEX in Seoul, serving as a guest speaker for a session titled “AI Recipe: The AI Built for My Brother, Evolving Into a Brand Verification Tool.” He presented alongside Yoon Bound Lab’s CEO, Cho Yong Min.
During the session, Lee discussed AI data crawling — a model that automatically collects and converts data from websites so that AI systems can immediately process and apply it. This technology enables real-time trend analysis, content recommendation, and automated generation across media forms like music, video, and text. It’s increasingly used in entertainment for fan engagement and content curation.
The expo organizers introduced Lee as a researcher at Unbound Lab’s investment team, specializing in AIX projects and advisory work for AI-related roll-up investments. They noted his background as a media major with experience at Cheil Worldwide and FengTai, two prominent marketing firms.
Lee is a graduate of China’s prestigious Fudan University and is currently an AI researcher at Unbound Lab. He first gained public attention when he appeared on tvN’s 'You Quiz on the Block' in June, where his striking resemblance to Cha Eun Woo went viral. He later appeared with his brother on tvN’s 'Finland Roommates' in December 2024.
Fans have since praised his achievements, saying he’s not only inherited Cha Eun Woo’s visuals but also built an impressive career in AI innovation.
