Maybe she just thought that she could fake the personality, and that he somehow wouldn't notice? Or she thought that he would like her more because she's the one who "made" him, so she knows him best. Idk, she doesn't seem like the smartest person
I'm a little confused here. Is the story following exactly how the author wrote it? Because it doesn't make sense. The ML already likes his wife, i think he'd be sad and angry if her personality changed abruptly and he'd hate the new isekaied girl. When was she supposed to replace the FL? He liked his wife from the very beginning so i don't see how he'd appreciate a new personalty for her...
