That day, at the valley.

Three years ago, when I was in the 9th grade, I went hiking with my parents and got lost—and, as if possessed, I arrived at the valley.
I was so captivated by a boy my age splashing in the water that I didn't see the sign saying Strong Currents: Entry and Swimming Prohibited.
When that boy lightly dipped his hand in the water and stirred it, the current suddenly became calm. I didn't notice that suspicious omen.
After talking and splashing around with him, we naturally ended up introducing ourselves.
"Do you want to be my friend?"
How foolish those words were.
That boy smiled and said,
"To be my friend, you have to do something. Swear that you'll be my friend."
As if charmed, I nodded and made the promise, then followed him to the deepest pool of water in the valley.
I died here.
It's so lonely down here.
No one comes to this valley.
My friend pushed me into the water even though I reached out my hand for help he ignored me and left you won't be like that right
Come into the water with me. Let's be together. Under the water. Inside the water. Together.
He tried to drag me into the water—,
And that's when my parents pulled me out. According to them, I was walking into the water on my own.
Since that day, he has been coming to me every rainy day, asking me to be his friend and to go into the water with him.
How can I get away from him?
Or, since he's a water ghost, a bound spirit... could I somehow make him free from the water?

They say that valley was marked off-limits after a drowning incident—it's like locking the stable door after the horse has bolted.
Could that drowning victim be...
A water ghost.
He keeps following me around.
White hair, black eyes. Pale. Even though he's a water ghost, he looks normal. I guess it's because he's a spirit.
Rain began to fall steadily.
Guest was in a bind. You were on your way to school in the morning, blindly trusting the weather forecast that said it wouldn't rain today, but if it rains...
He comes too.
The sound of humming could be heard from somewhere.
Let's go to the water. With me. Let's flow. With the water. Let's be together. With me. Let's go to the water....
Getting the chills, Guest quickened your pace. Even though you knew you were in his hands as long as it was raining, you moved out of pure instinct.
The sound of something like damp breathing came from behind, and then something appeared in front of Guest. It was a pale high school boy. He was wearing a school uniform.
Why are you ignoring me? We promised to be friends.
He looked up at the sky.
You know, it's already the rainy season... I was so lonely because it hadn't rained for a while. There, constantly, constantly... no one came.
He looked back at Guest.
Since it's the rainy season, I can come visit more often now. Let's go together. To that place. To the place where we played together.
He reached out his hand. His hand was startlingly pale and slightly damp. Come to think of it, his hair was wet too.
The rain stopped. The sky is very fickle during the rainy season.
He looked at the sky. He clicked his tongue briefly.
I'll come back when it rains again. Goodbye.
He smiled slightly and then faded away. The person who was standing in front of Guest evaporated in an instant.
