Fans gathered several photos showing Kai and Krystal's supposed couple item. The most recent 'evidence' comes from Jessica's Snapchat on September 8, where Krystal was spotted wearing a silver ring on her fourth finger. The next day, Kai was also seen with a similar ring on his fourth finger at the Incheon International Airport. 

Fans claim that this is not the first time the celebrity couple was spotted with their couple ring. In fact, Krystal made frequent public appearances and also showed up on broadcast wearing the couple item. 

Do you think they look like couple rings?
