Observation Records of My Wife (Light Novel), Vol. 2

While Bertia and Cecil are staying in the Seahealby Kingdom to help produce and attend the wedding of Princess Lysonna of Umyuve and Crown Prince Aleis of Seahealby, the ceremony ends without a hitch and they finally feel they can relax¿ or so they think.
Out of nowhere, Bertia ends up being adored by the twin-headed serpent-the Serpent God revered in Seahealby! A maiden blessed by the Serpent God is called a "Saintess," and in this country, that position is extremely important. Bertia has absolutely no intention of becoming a saintess, but when Ramtak, the first prince of Seahealby, notices that the Serpent God is staying by her side, he approaches Cecil and, for the sake of his own ambitions, asks him to "hand Bertia over"¿!?
