The Wicked Saintess Wants to Help Her Beloved Husband (Although, Doting Affection Was Unexpected)

I woke up with no memory. Apparently, I was a 'rare saintess' with considerable power, but it seems to be sealed now. But that's not important... "...My husband is too handsome...!?" My husband is so wonderful that everything else is trivial!! However, before I lost my memory, I was a villain who misused the power of the strongest saintess and did cruel things. Master Ozwald, a genius magician, reluctantly married me as my 'only one who can kill me' supervisor. I've lost my power as a saintess, and everyone around me hates me. More than anything, my new husband hates me... (I'm a wicked wife. I'll keep the fact that I lost my memory a secret.) As atonement for my evil deeds as a wicked saintess, I want to help my beloved husband as much as possible. "If you help Master Ozwald, will you go on a date with me!?" "Hmph. If you really can, I'll hold your hand and go on a date or whatever. ...Understood, get away from me, don't hug me!!" ...But, I feel like I can use the divine power that was supposed to be sealed...? ★This is a new marriage romantic comedy about a 'dog-like unfortunate saintess whose (husband) crush makes the air delicious' and a 'genius magician husband who is cold to his wicked wife but is unknowingly bound by irresistible forces'.
