An Agrimony person will not reveal and hides her feelings from others.
She will always be smiling, hiding the worries inside. If you look at her you can’t figure it out as she hides her inner turmoil.
If she takes Agrimony, she will reveal her feelings to you.
If she is not willing to take it then you can chant Agrimony visualizing her. She will definitely come out of her shell.
