"Do you wanna be with me?"

Saint Blanche continued to fulfill her duty as the Saint, even while being oppressed by her fiancé, Georg, the prince of the neighboring country. However, she was suddenly told that her engagement was canceled-because Georg had found the "true" Saint-and exiled Blanche from the country.

Blanche returned to her hometown, but... her worried brother suggested that she make a fake engagement with her childhood friend, Raymond. Suddenly turning into a C-childhood crush to a fiancé, Blanche is constantly flustered by Raymond. A love fantasy of unrequited love begins to unfold from their fake engagement!
