My Husband Is Definitely a Paladin

My Husband Is Definitely a Paladin
The protagonist, Irene, possessed the power to purify demonic energy, but because it was deemed the lowest grade, she was never loved by anyone. She died alone and lonely in her final moments, but when she opened her eyes, she had returned to the past. Specifically, just before meeting her husband, Michael, whom she had ruined in her previous life. But Michael is strange. A paladin who should be as pious as a priest, he comes to find her every night. ‘Irene, my wife. Tonight, I wish to receive your purification.’ You were the paladin who didn’t want to touch me even with a single finger in my past life, weren’t you?
