Princess Kwon Hyunbin has been betrothed to King Kim Donghan since he was a child and was made his Queen. It didn’t take long for the two to fall in love, with Hyunbin’s heart never leaving his King and Donghan's eyes never leaving his Queen.

Until the appearance of Japanese royalty Takada Kenta.

i.e. Just trying to satisfy my Donghan Hyunbin love hate relationship obsession.
