Wasn't his name also Ciel while he was on earth? And didn't she know him as that, and in fact he looks the same. Wasn't she the one who crushed on him, or caused some trouble between him and his wife or something? I guess I could go back and look. But she arrived with her memories, and I think Ciel recognized her as well.
I had forgotten they went back in time.. Still, it feels like convenient plot devices, Ciel remembers all.. Irene remembers all, the saintess only remembers her life in korea before she came. Well, I guess we could assume it's a god helping the main couple, but the saintess has some sort of game console?










The fmc was completely unnecessary in this story. except for the smut I guess. I don't mind a mmc centric story.. but they make her useless and wearing that stupid , ugly hat throughout most of this story, haha.. imo she couldn't be more lame.
