The main reason I loved Night Light is the relationship between our main female leads, Seo Yi Kyung and Lee Se Jin. In the beginning, there are a lot of mistrust between them, but they grow to care and love each other throughout the story. I fell in love with both Lee Yo Won and Uee in this drama! Yo Won plays a smart, cunning woman who'd do anything to achieve her goals. Uee gives life to Lee Se Jin, a poor woman whose ambition grabs Yi Kyung's attention. Yi Kyung is cold, but we can see hints of vulnerability, something that really drew me to her character. I loved how capable she was: watching her outsmart those men who were older than her (and who underestimated her) was extremely satisfying. Se Jin was much more light-hearted (at least in the beginning), she smiles and jokes a lot, but deep inside her was a desire to reach the top, something that Yi Kyung saw and wanted to use. Their relationship is complex, as we don't know exactly how they truly feel about each other: do they trust each other? will they betray each other? But the answer becomes clear, because we can see these two women, who have personal goals on their own, grow fonder of each other and even giving some of those goals up in order to protect the other. Their relationship was truly fascinating. I've never seen another drama that focus on a relationship between two women and I honestly don't think I'll get something like this in the near future. As I said, Se Jin and Yi Kyung were my favorite part of the drama, so I was able to easily get through the aspects I wasn't a fan of: the business talk, the slow pace, scenes that were too dramatic. It was so interesting and satisfying seeing two women being successful in an old-men dominated field, that I didn't care for these downsides. Night Light is an interesting drama that focus on its female characters and the relationship that forms between them. If you don't like business or slow paced dramas, this might not be for you. But if you want an unique drama that portrays a complex, intense relationship between two ambitious, intelligent women, this could be perfect for you.
