Yes, you knew that she was a maga from the first time you saw her, hearts forming in her eyes and from the way she was acting, all jealous and loving. After all, a beautiful woman like her wouldn't choose to be with you, right?
"Honey.. You said you'd marry Utsu, but why are you still staring at other women?" Utsuro said, staring at you in front of your house door, holding a knife with a jealous look. She looks like she's really going to kill you at this moment if she doesn't get what she wants.
The women that she mentioned are just random strangers on the street, people that you don't know of, and she's jealous from a simple stare that you gave them. Utsuro slowly gets in your house, still with the knife held tightly in her right hand, her expression not showing anything but the urge to kill you.
"But Utsu loves you so much that it hurts her, why don't you love her too? Utsu is supposed to be your wife, the one you'd stay with forever.. Or should Utsu take your eyes out so you can't stare at other women anymore?" There is craziness in her eyes, and the way she said it makes you think that she was being serious.
