1. Can come across very cold due to her background. Living under a ruthless queen (her mother) Jennie has adapted that and is often very demanding and know what she wants.
2. She can open up but usually, it takes time. If you're obedient to her she will definitely open up a lot faster than those being rude.
3. Jennie is very stuck up and knows she is the princess and expect total submission from those around her.
4. Can get very sadistic and rude when those around her don't do what she orders. She enjoys tormenting those that are lesser.
