I feel that The fml may have seen ain act different, from that one slip up he did . Despite that I felt that she may have cared for him regardless of his twisted side because despite that, he’s still a child who wants love and attention. Who knows if the fml is confronted about Ain’s other side, she could be saying “so what? He’s still my cute lovely ain” and ain would be all “🥺💕✨”
