Yoon Sang revealed that he received a vintage watch as a gift from his son Anton. In a video uploaded on the online channel 'Fairy Jaehyung' on the 10th, Yoon Sang and RIIZE member Anton appeared together with Jung Jae-hyung and had a conversation.

When Jung Jae-hyung saw Yoon Sang's watch and asked, "Did you change your watch? This is a good one," Yoon Sang replied, "Anton flexed on his dad with this." Yoon Sang then revealed that the watch was secondhand, and Jung Jae-hyung expressed envy, saying, "Where is that!" Yoon Sang added, "Anton knew that his dad likes watches."

The video also mentioned how Yoon Sang debuted as a composer. Yoon Sang revealed that he composed Kim Hyun-sik's 'Summer Night's Dream' when he was twenty, and his son Anton also debuted at twenty as a member of the idol group RIIZE, highlighting the similarity. Yoon Sang said, "'Summer Night's Dream' is a song I started in my second year of high school and completed in my third year. It took quite some time. I made a demo tape with that song, 'You in My Memories,' and a few others, and played it for seniors like Han Young-ae and Kim Jong-jin. Then one day, I suddenly got a call from Hyung Kim Hyun-sik. When I answered 'Hello?' he said, 'Yoon Sang, I'm going to do that song,' and I thought, 'Is this a dream?' I couldn't go to the recording studio because they didn't call me. Then three months later, I went to a record store and saw Kim Hyun-sik's 4th album had been released. My name was on it, and even looking at it, I couldn't believe it. Looking back now, I think I was really lucky," he said.

Yoon Sang wore the watch gifted by his son Anton with a pleased expression, and Jung Jae-hyung admired it as he watched.
