I'll Never Be Your Crown Princess! - Betrothed (Manga) Vol. 4

Being cooped up indoors has never suited Liddy. But with the threat of harm from the Kingdom of Sahaja still lingering, she has had no choice but to stick close to Freed--in more ways than one. When he suggests they go on a clandestine date in the city, Liddy jumps at the opportunity for some fresh air and fun! The details of their outing remain a secret, yet the closer they get to their final destination, the more strangely her princely fiance begins to act. Just what kind of surprise does Freed have up his sleeve?
