“CC” is short for “campus couple.” The “Boys over Flowers” co-stars, Kim Bum and Kim So-eun have supposedly taken their onscreen love offscreen. The snake-eyes of netizens have spotted the pair wearing the similar couple rings (which proves that they are dating!). Not only that, their lovebird status is also common knowledge at their university, Chung-Ang University where they have enrolled in the Film and Theater Department.
Netizens have found that the two are wearing the same ring, also known as the oh-so-popular couple ring. But a misconception is the fact that So Eun wears her ring on her index finger while Kim Bum’s is on his ring finger. Not only that but they both wear it on different hands, too. I mean the rings do look pretty similar but Kim Bum’s picture of his ring is still too small to say the rings are the same. Maybe So Eun was trying to avoid rumors but Kim Bum didn’t care about stupid rumors.
