While the broadcast continued, fans noticed one other thing about the two stars; they showed extreme similarities in terms of the way they looked.
Following the broadcast, a lot of fans talked about that.
Actually though, Taeyeon commented on this interesting fact before.
At that time, she said, "Whenever KEY happens to pass by me, I think of my older brother. KEY really reminds me of him."

Under a photo of KEY having a snack at a theme park, Taeyeon wrote, "Wow, I honestly thought you were my older brother."
She then left another comment saying, "I'm still so shocked. I thought my older brother had gone to the theme park. Aren't you Ji-woong (the name of her brother)?"
