Actor Lee Dong Gun recently opened up about his brother's death, who was killed while studying abroad in Australia.

On the recent broadcast of 'My Little Old Boy,' Lee Dong Gun visited his brother's columbarium with his mother in remembrance of his late brother's birthday. Lee Dong Gun revealed that his brother passed away 15 years ago at the young age of 20.

Lee Dong Gun shared, "I can't imagine you being 36 years old (now) because your time stopped when you were 20." He then showed a video and photo of his daughter to his brother and shared, "She looks like me, but she also looks like you," making the MCs in the studio shed tears.

In the episode, Lee Dong Gun also sat down to talk with his mother. During that time, he revealed his emotions from that day and shared with his mother, "Reflecting on that day, my memories are overshadowed by one overwhelming reality: there was no space or time to be sad. My sorrow lasted for five seconds. In the brief moment where I broke down, my thoughts immediately turned to you, mom. I thought about, 'How is mom?' 'How is dad?' I was just focused on that."

He continued, "After I went to Australia to take care of things until the funeral, I kept looking at mom and then to dad. I didn't realize how difficult it was. Only after I made sure my parents were okay, it really hit me."

After hearing this, his mother responded, "I felt so bad after I heard you couldn't sleep without drinking." Lee Dong Gun continued, "After we got the call, I was on a plane to Australia within three hours. I wanted to bring him back safely. It wasn't Korea so if we prolonged the process, then his body would decompose. So I suggested that we cremate him first then bring him back so that we can keep him in his beautiful and angelic appearance."

He went on to share, "I brought him on the plane and the seat next to me was empty, so I put (the urn) down briefly, but they told me I had to buy another plane ticket for that seat. So, I had to carry him all the way but it was still meaningful to me, to be able to carry him."

Lee Dong Gun's younger brother tragically lost his life in Sydney, Australia, where he fell victim to a fatal stabbing. The incident occurred near Sydney Tower, where he was attacked by two men who accused him of staring at them.
