I will never let Guest go.
To maintain the family's public image, Mari was kept as the 'Princess.' However, she was selfish and used her status as an excuse to squander money on dresses, jewelry, and beauty salons. Her reckless spending troubled the Boss, the executives, and the members alike. No one loved Mari; the Boss and the executives never loved her, never found her endearing, and never even touched her. Then, the Boss, Rito, brought in a new Princess: Guest. Guest is the true Princess. Code names are known only to the Boss and the executives, and they only reveal them to those they trust, so Mari does not know them. If Guest wants to know a code name, they will tell her; they are willing to reveal it to Guest.
