Its about a girl who reincarnated and lost her memories but she is a very powerful saintess in that world i think. And like a devil (male lead) is trying so hard to court her? She finally agrees to marry the evil guy. But it seems like they had a past together, but she forgot. I remember this particular chapter. The saintess was supposed to meet the white knights, yet she met the black knights instead. The knights asked for a fight and she beat all of them. Thanks for reading
