After losing my memory, I worked part-time at a courier station to make ends meet.
However, the fiancée broke the engagement in public and turned around and threw herself into the arms of a wealthy young man.
Until that day, a mysterious package that could not be delivered was sent to me——
Inside are twelve blood-stained family crests,
And a secret command that only I can understand:
"Your Highness, the traitor has been identified. Please come back... Hold the sword."
