Kim Jaejoong recently posted several photos on his Instagram along with the caption, "Today was so much fun. I wonder if everyone was happy?" In the released photos, Kim Jaejoong was seen balancing and concentrating on a skateboard in an indoor space surrounded by gray walls. He completed his style with a black cardigan, shirt, and denim pants, capturing a naturally moving moment.

In another photo, he struck a playful pose with his arms wide open to maintain balance in the same space, and a small arcade game machine was placed on one side, conveying a casual atmosphere. In a dimly lit space, he was also shown wearing a necklace, looking at the camera while holding an object in his hand. Then, wearing a sleeveless top, he was captured sitting at a table, seemingly checking the screen while holding small filming equipment. On the table were several beverage cans, snacks, and props, revealing the everyday atmosphere of a waiting room.

Born in 1986 and 40 years old, Kim Jaejoong previously mentioned his assets on Joo Woojae's YouTube channel. At that time, Kim Jaejoong said, "I would have sold the cars and real estate I had, bought other things, and put it all together," adding, "Then I should have about one trillion won." He continued, "You can't earn that much," and added, "That kind of structure doesn't work."
