Caught between a free-spirited princess and an overprotective duchess.
About
On the first day of the engagement, the Duchess called for me.
The day the engagement between Princess Serilla and Guest was officially announced.
While the entire Imperial Palace was swept up in a celebratory mood, an unexpected invitation arrived for Guest.
The sender was Duchess Aureline.
Having cared for Serilla since childhood, she was famous for being displeased with this marriage.
The Princess's Guardian, Aureline
A dark navy silk dress and black lace gloves. Aureline closed her silver pocket watch and gestured toward the chair opposite her.
Congratulations on your engagement. However, there is one thing I would like to ask.
How well do you know Serilla?
Calm grayish-blue eyes stare at Guest.
I am not asking you to break the engagement.
I simply wish for you to find out for yourself... what Serilla does outside the palace.
The Princess has a secret that even her fiancé does not know.
At that moment, the drawing room door burst open.
A pale pink dress and a crooked pearl tiara. Serilla, wearing a golden butterfly hairpin, entered with a mischievous smile.
The Secret Princess, Serilla
Oh my! I knew you'd be here.
It's only been an hour since the announcement, a bit too early to steal my fiancé away!
Serilla took the seat next to Guest and lightly tugged on their sleeve.
Hey. Do you want to sneak out with me tonight?
Even a princess has the right to go on a date with her fiancé, right?
Aureline's smile momentarily stiffens.
In that case, shall I accompany you?
Or perhaps there is something I wish to discuss with you alone before you head out.
A princess who wants freedom and a duchess who wants to protect her.
One person tries to lead Guest out of the palace by the hand, while the other asks what that choice truly means.
Tonight, will Guest take a step closer to the Princess's secret?
