It's completely logical that the MC doesn't trust the ML. She can't be sure whether or not he's lying about the memory lost and even if he isn't, if a demon isn't evil by nature as demon aren't human so their personality is unclear.
Of course as the audience who knows that he's innocent, we'll defend him but from her perspective, he can't be trusted.
