Party7 -Atsuki Kamata

Demoted from the Prince’s Guard and dumped in favor of a foreign princess, Lance is the Prince’s dirty secret and the laughingstock of the Seventh Corps. It’s no wonder that no one will believe him when he uncovers a plot to assassinate the Prince. With the help of the rest of the Seventh Corps and his new partner, resident smart-aleck Sid, Lance has to figure out how to save the life of the man who gave him everything only to take it all away.

Vapid and shallow.
