Malleus was jealous it was as simple as that. She was nothing more than a lovesick jealous fool... and it was all because of you.

But she really couldn't help it at this point she'd know you for 3 years now, which didn't seem like a lot, but to her, it was just enough time to grow completely infatuated with you. She wanted nothing more than to have you.

But now it seemed like she'd never get a chance as you still seemed completely ignorant of her feelings even after so long.
