Looks and brains clearly run in this family!
ASTRO’s Cha Eun-woo (real name Lee Dong-min) has a younger brother, Lee Dong-hwi, who’s been making headlines not for his looks this time but for his brainpower. The rising AI expert recently took the stage at the “AI Summit Seoul & Expo 2025”, impressing audiences with his tech knowledge and charisma.
From Celebrity Brother to AI Innovator
Lee Dong-hwi joined Yongmin Cho, CEO of Unbound Lab, for a talk titled “AI Recipe: The AI Made for My Brother That Evolved into a Brand Verification Tool.”
According to the official AI Summit Seoul website, Lee currently works as a researcher at Unbound Lab’s investment team, specializing in AIX (AI expansion) projects and consulting for corporate roll-up strategies.
A graduate of Fudan University in China, he previously worked at a major Korean advertising agency before joining the AI startup world.
And yes the description on the conference site even proudly notes: “Younger brother of actor Cha Eun-woo.”
Built AI Tools for Celebrities Like His Brother
Sources say Dong-hwi’s personal motivation came from wanting to create something useful for entertainers like his brother Eun-woo. His research focuses on AI data-crawling models systems that collect and analyze web data in real time to help brands and entertainment companies manage their image and reputation online.
Imagine an AI tool that helps keep track of global fan trends, articles, and brand mentions — built by Cha Eun-woo’s own brother. Talk about family synergy!
Netizens Can’t Get Over His Visuals
Of course, this isn’t the first time Lee Dong-hwi caught public attention.
Back in June, he appeared briefly on tvN’s “You Quiz on the Block”, and fans immediately noticed the tall, handsome man walking in the background later revealed to be Eun-woo’s younger brother.
Even ASTRO members have joked that “Eun-woo’s brother’s face is even smaller and more handsome.” Fans couldn’t agree more now calling the Cha family “genetically blessed and intellectually gifted.”
AI Meets K-pop Stardom
The AI Summit Seoul & Expo 2025, co-hosted by KITA, COEX, and DMK Global, gathered top Korean and international tech companies to discuss the future of AI.
But let’s be real few expected one of the most talked-about names to be Cha Eun-woo’s brother.
It seems like talent truly runs in the family — one takes over the stage, the other conquers the world of AI.
Netizens Can’t Get Over the “Gene Pool”
While his brain is the headline, his visuals remain a viral topic. Following a brief 4-second “accidental” appearance on tvN’s You Quiz on the Block last June, fans have been scouring the web for more info.
ASTRO members famously joked that “Eun-woo’s brother has an even smaller and more handsome face,” a claim that seemed impossible until Dong-hwi stepped into the light. Netizens are now calling the Lee brothers the “Ultimate Genetic Lottery Winners” one conquering the stage, the other the future of AI.
