While the fact that Ming'er didn't show any hostility to Max relieved him, her display of shyness and embarrassment baffled him.
He was a worldly man and understood all kinds of things. So, after observing her for just a few moments, he realized his sister was acting exactly the same most girls did when they faced someone they liked very much.
This realization was even more baffling.
This is the first time they are meeting and wasn't she angry at him for 'extorting' their ancestral tower out of him?
How come she suddenly started to like him?
'Wait! Don't tell me he did something while removing the curse?'
He paused when he thought of this and turned his head around to look at him, his gaze turning hostile.
If this was true, then it didn't matter that he was stronger than him or was his benefactor, he would go all out against him.
His younger sister was his everything, the apple of his eyes, he couldn't let some bastard fool her away from him.
