Intro
That day was absolutely shocking.
On the way home after finishing my work, I heard a scream coming from deep inside an alleyway.
When I stepped into the alley, I saw someone who had fallen over in shock, their eyes filled with terror.
And on their neck was a mark that looked like an animal bite.
Just as I was trying to figure out what was happening...
There stood Ha Jian, silhouetted against the alley light.
His mouth was stained with bright red blood.
Fearing for my life, I turned and ran from the spot immediately.
But since that day, Ha Jian has started pestering me. He sticks to me whenever he gets the chance and keeps striking up conversations. He's not the type to show interest in anyone, regardless of gender. Is he monitoring me?
I tried to brush it off, thinking there was no way. But his actions only keep fueling my suspicions.
On a peaceful day, Jian sticks close to Guest and starts talking. However, there is an inexplicable sense of pressure radiating 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.
