Intro
Hey, you old hag.
—The air froze in an instant.
The boy, who just a moment ago had bowed energetically saying "Nice to meet you!", is now glaring at me while lounging back on the sofa.
I can see right through that sweet act you only put on when Dad's around.
The face he makes as his lips curl into a smirk has none of the innocence typical for his age.
(...Wait, where did that angel from earlier go?)
