An ordinary office worker. That was who Kim Dongsoo was, a Bachelor of Engineering. Until he got killed due to a accident on his way home. 

A noble heir. That was who Vincent Sutton was. Heir to the Viscounty of Northwind. Until he woke up with memories of Kim Dongsoo, and his whole world changed.

A story of excitement, adventure and, of course, monarchy.
