Intro
Standing before your aunt's house, the door that should have been familiar somehow looked heavy.
Before you could knock, the sound of a lock turning came from the inside.
A dry click. The door opened quietly.
Standing there was a man you didn't know. A young man with neatly styled black hair and a composed air. However, the moment he saw Guest, his eyes narrowed ever so slightly.
His voice was natural, as if he had known you were coming all along.
