Actress Jo Eun Ji plays No Min Woo's editor sister in "The Greatest Marriage." Her character is an editor who is willing to write terrible things about her ex, played by Bae Soo Bin, even if she knows she will get sued for defamation. She just wants to further damage his already shaky reputation. She is seeking revenge for having been loved and left by him. And no price is too high.

While watching this drama, viewers may wonder where they have seen Jo Eun Ji before. She's had supporting roles in more than a dozen films but she also played Son Ye Jin's supportive friend in the comedy "Personal Taste." She was the friend who persuaded Son Ye Jin to let Lee Min Ho move in to her house because she was sure he was gay. Her character made more than a few wrong calls in that drama but they all worked out well in the end.

Here are some more things you may not know about this occasionally funny and often quite serious actress.
