Damsel in distress

Her?

I frowned a bit as I peered into his eyes.

Who is the 'her' he kept on mentioning?

“What a joyous day this is for me.” He sighed, “I will get revenge for all the humiliations brother put me through.

Just like I did the first, I will do it to this one, and all the human-pet he might get. I will make him experience what it means to go through so much intense pain, it hurts just thinking about it.”

The more the man spoke, the more confused I got.

I just didn't understand his words at all.

“Let's go.” He said before he started for a direction opposite the one master intended to take, before the appearance of the female caused him to deviate from the path we were walking on.

I followed him like the puppet I was turned into.

A few of the maids, we saw, didn't spare a glance at us as they hurried.

They only bowed at master's brother before they hurried off to wherever they were going.
