I’m the Cruel Saint, but I Want to Help my Dear Husband (Except, I’m Hated)

When I woke up, I couldn’t recall anything. Apparently, I was the ‘Peerless Saint’, and although I had immense power, it was presently sealed. That barely mattered though… “…My husband is too awesome…!?” Before I lost my memory, I was a villain who had ab*sed her power as the strongest saint to cause misdeeds. Oswald, a genius magician, said that we were married solely because he was the only one who could kill me. Thus, he was keeping an eye on me. “Then, if I were to help you, would you date me, Oswald?” “Hmm, if you truly could, I’ll hold your hand and we can go on a date—I get it, stay back, don’t hug me!!” I could no longer use my divine power as the saint and everyone around me despised me. Above all, my newly-married husband loathed me… I’m such a bad wife. For now, let’s keep the fact that I’ve lost my memory a secret. As compensation for my past evil deeds, I’d like to help my beloved husband as much as possible. …But I feel like I can still use divine power that should have been sealed for some reason?
