Dekiai Ou wa Boukoku no Oujo wo Nigasanai: Fushidarana Mitsugetsu to Kouketsu no Chigiri

When Anais wakes up, she finds Octavian, King of Barbier, by her side. He tells her they are husband and wife, and he is devoted to her, even though she has lost her memory. Anais is overwhelmed by his tenderness, sweet kisses, and hot caresses, and she is unable to think deeply about the situation. She tries to recall her memory, but Octavian insists that she does not need to force herself to remember, and dotes on her even more fiercely. He even prepared a fantastic hanging garden as a gift for Anais, "all for the sake of my beloved wife." Anais spends her days without contact with the outside world, but she soon discovers that Octavian is hiding something from her.
