The following day...
Malaya saw the familiar surroundings as soon as she stepped through the academy gates. Along with the invitation to the foundation ball, they also sent her a note informing her that a new dorm was being prepared for her. Not only that, but they promised her that the event would never happen again and even reinforced the academy's security system.
'Well, just my hunch but I think no matter how much this school enhances their security, that witch will still be able to enter whenever she wants.'
They also informed her that, aside from the headmaster, a few higher-ups at the academy, and the Marina duchy, no one else knew the true events that occurred in Malaya's chamber previously. They just informed the remainder of the students that the explosion was the result of a faulty experiment.
