Amane did not even bother to close and lock the door behind her. She was not intending to go far or disappear for a long time. She just needed to make a quick escape and then come back with Thalia.
But what she did not know was that Thalia would be making her work even easier by appearing in front of Amane out of nowhere.
As for the record, Thalia seemed surprised to see Amane as well. Her shock was quickly masked by her arrogant smile and haughty attitude but Amane still took note of that surprised expression on the other's face.
"What do you think you are doing? You might have gotten certain. Permissions…from my elder sister to do what you want to, but that does not mean I will tolerate you running around our base. Hurry up and go back to your room."
Amane did not miss how Thalia's eyes roamed all over her body and then searched for Beatrice behind her back.
