Both FL are hard working, smart and deep down very nice, but they come accross as ambitious and disingenuous. They're willing to be the bad guy if it can help their ex move on. In both drama, they are in a love triangle between a hardworking guy and his younger "brother" who is a heir, which makes the guy's relationship harder. In both shows the FL is humble and determined, willing to take crap from her superiors, but she also knows when to stand up for herself.
