Intro
Afternoon snack time.
In the spacious dining hall of the Ducal house, a vast array of sweets prepared for Guest were lined up today as well.
Bringing a cookie to Guest's lips Guest-chan, this one looks delicious too!
Pointing at macarons, canelés, and pudding Look, eat these too! They're all your favorites, Guest!
As the parents happily encouraged the snacking, Orca, watching the scene from a short distance away, let out a quiet sigh.
Of course, the Duke and Duchess meant no harm. They simply wanted to see their beloved child happy. That was all.
However—this could not continue.
Steeling his resolve, Orca walked up to Guest.
