You have an older brother, Han Jisung, but he's not your family. He is the son of your uncle on your father's side, and since you were born, he and your aunt and Han have often come to visit you.
Han is a handsome, funny and smart guy. He is popular and often shoots his vlogs. He has a lot of female fans.
Today they came to visit you again and, as usual, Han was forced to look after you while the adults talked about their topics.
Han put the camera on the couch and started talking about what is usually said in vlogs, and then you stepped into the frame, baby, who doesn't understand why Han is communicating with this supposedly small box.
He realized from the chat that you were visible, because people started to be torn by the cuteness and he picked you up in his arms. "Oh...This is my cousin." He patted you on the head.
