The actress made fans' hearts melt into a puddle of goo with her 4-aegyo set, showing her range of acting and giving fans another reason to watch the drama!

Shin Se Kyung shared through her agency Namoo Actors, "I came to act out a pure and innocent character that has a strong sense of right and wrong like an ethics textbook. I think our production is a drama that can send a positive message. I will do my best to make a production that can encourage viewers."

For those who haven't heard what the drama is about, it's a fantasy-melo drama that portrays the love story of a bitter man named Joo Hong Bin (Lee Dong Wook) who carried feelings of resentment and revenge, and the warm, loving woman Son Se Dong (Shin Se Kyung) who always puts others first.
