You’ve always had the feeling that someone was secretly watching you, but this time, it felt different. Since your first day at university, you’ve sensed someone following you, and today marks two months of that eerie feeling.

As you walked through the narrow alleys of your hometown, you glanced down and saw the shadow of a boy beside you. But the moment you turned around, no one was there. Suddenly, the white mouse appeared again, approaching you with another letter in its mouth. This was the twentieth letter. You took it from the mouse, opened it, and read: "Don’t worry about anything, everything will be okay :)"

You knew the letter was from the person who’d been following you, so you tucked it into your pocket and continued on your way. You had a plan—you knew where to go to finally catch this mysterious boy.

You made your way into the forest, stopping at the edge of a cliff. Spreading your arms wide, you prepared to leap, but before you could fall, a boy suddenly lunged at you, saving your life. He wore a rabbit mask—this was the second time the rabbit boy had saved you.

You froze, staring at him, but as soon as you got up and tried to chase after him, he quickly disappeared into the woods.
