Kim Taehyung - King

In order to rule one of the seven kingdoms, Kim Taehyung agreed to a marriage with Princess Sana. The arrangement was perfect, as she retained her freedom and he could continue secretly loving Jeon Jungkook, his private investigator and trusted spy.

After months of gathering secrets from the other six kingdoms, Jungkook returns from his latest mission ready to deliver his report. As usual, he locks himself away for days in the royal office with the king. However, during this last visit, Jeon Jungkook becomes pregnant. The problems escalate when Sana confesses that she, too, is expecting a child with her lover.

With two hidden pregnancies progressing simultaneously, Taehyung and Sana race against time to defy the kingdoms' traditional laws and pass a decree allowing a young man to be married to the king.
