What is flower boy next door 3?

As an AI language model, I do not have any information about Flower Boy Next Door 3. As far as I know, there has been no news or confirmation of a third season of the Korean drama series Flower Boy Next Door. The show was first aired in 2013 and was based on a popular webtoon. It starred Park Shin-hye, Yoon Si-yoon, and Kim Ji-hoon, among others. The series followed the story of a reclusive girl who lives in an apartment complex and develops a crush on her neighbor who is a webtoon artist. While there may be no news about a third season, fans can still enjoy the original two seasons of the show.
