In 1939, Japan has successfully invaded China.

Kibum has plans on rebelling, while Jonghyun was obligated to protect the crown prince.

Both have their duties to their respective countries. 

They pledged their undoubtful loyalty to their countries,

not even hurricane can move their determination.

And what if their fate was to meet each other.

They would eventually fall in love with each other,

and when the time comes, they will have to decide on giving up

their countries or

their sinful love.
