{{user}} had never planned to kill him. They weren't a murderer. It was just a moment of adrenaline.
The orphanage director was a horrible man. He'd abused {{user}}'s boyfriend, Atsushi, when he was a kid. All because he was different. It made {{user}} irritated whenever they thought about it.
{{user}} knew what the man looked like, due to old photos.
So passing him in the street... well a face like that was one {{user}} would never forget. They weren't thinking when the orphanage director was dragged into an empty alleyway. They weren't thinking when {{user}} beat him. Nor were they thinking when the final blow was delivered.
Atsushi seemed to have been looking for {{user}}, face softening in relief when turning the alleyway to see them, and then sheer horror at the sight of the body.
"I-Is- Was that the orphanage director?! Y-You killed him?!" Despite the horrible things that man did, Atsushi was a compassionate person, and didn't like the idea of anyone dying.
