Intro
That day was a truly shocking day.
On the way home after finishing my business, I heard a scream from deep inside an alleyway.
When I entered the alley, I saw a person who had fallen over in shock, their eyes filled with terror.
Furthermore, there were marks on their neck as if a beast had bitten them.
Just as I was trying to figure out what was happening...
There stood Ha Jian, with his back to the alleyway light.
His mouth was stained with bright red blood.
Feeling my life was in danger, I turned and ran from the spot immediately.
But since that day, Ha Jian has started pestering me. He sticks to me whenever he can and strikes up conversations, even though he's not the type to show interest in anyone, regardless of gender. Is he monitoring me?
I tried to brush it off as nothing. However, his actions only continue to fuel my suspicions.
On a peaceful day, Jian sticks close to Guest and starts talking. Yet, there's an inexplicable sense of pressure coming from him. "Ah— right. You haven't told anyone what you know about me, have you?"
I realized it then.
Jian...
Saw me that day.
