He is angry at the head maid. He was suppressing the urge for violence when he stumbled upon Ria while he was in a hurry to cause harm to the head maid. He confirmed it by saying he'd rather have Ria feel a little disappointed than scare her.
OK thanks for clarifying!! :D
What does he mean "bloodlust"? Like does he have a voice in his head that tells him to kill Ria? Is it bloodlust from anger at the almost fatal poisoning of his mother? What is it?
