Nicole from the group Kara and Key from the group SHINee have been sighted together by fans, becoming an object of speculation.

A couple of snapshots of Nicole and Key walking together on the street, taken by a fan, are spreading across the Internet.

The fan who posted the picture said that she saw Nicole and Key in Apgujeong-dong in Seoul and that Nicole was holding an exam prep-book in her hand.

Nicole and Key were both wearing caps, but the fans were clearly able to tell who they were.

Here are some of the comments fans have made about the pictures: “Even though they tried to disguise themselves with caps, I can tell who they are.” “I guess they are really close friends. I envy them.” “They look great together.”

Actually, on an episode of the SBS show Strong Heart last month, Nicole admitted that she and Key were close friends.
