Sure, find out what'll happen

John: I am pretty curious. Please tell me.

Anegl: v-very well. my angel's name is...i-is...sahaquiel.

The room changed from the Noh stage to a marble room. In the middle was a beautiful wooden desk and a chair facing away from you and the angel.

?: You told him your angel's name, Sahaquiel.

Angel: i know, i'm so sorry. but....i was unable to say no to him.

?: I know, it is your nature to be obedient. John, why did you ask this angel her true name when she said she could not tell you?

John: it was only curiosity. i meant no harm.

?: I am aware of your lack of malicious intent. However, making an angel do something she knows she must not simply to satisfy your own curiosity is not something I can tolerate. Do you know what will happen now that you know this name? One cannot forget the name of an angel once told. Once born, you will be able to see your guardian angel for the rest of your existence.

John: forgive my asking, but why is that a bad thing?

?: Because if you can see her, you will look at nothing else. You will not seek a human mate and will not be fruitful. Your life will be lonely, as she cannot directly interact with you. I have only one option. John. You are denied a guardian angel.

John: what!?

?: I am withholding your guardian angel from you. Sahaquiel, you are expelled from the guardian program. I am demoting you to to service angel.

Angel: ...yes.

The angel bows her head and several tears fall to the floor. She looks heart-broken.

?: She is heart-broken. She has been attempting to enter this program since she arrived 290 years ago. This is not an insignificant loss for her. Were she capable of hating you, she would.
