It was deep in the mountains that she and I met.It's been about two hours since she started walking into a steep mountain in search of the legendary lake her grandmother had told her about.When I suddenly stepped out of the dimly-grown trees into an open space and squinted my eyes at the dazzling light, the next thing I saw was a deep blue water surface that seemed to draw me in.Taking a deep breath and looking around, I was convinced that this was the legendary lake. ――What is the legendary lake?It is located deep in the mountains of the Tohoku region.A long time ago, a beautiful girl drank water from this lake, wishing for immortality.This terrifyingly delicious water never gets tired of drinking, and it is said that it actually makes you feel more thirsty.Her daughter, who was possessed by her charm, fulfilled her wish and became immortal, but at the same time she became a big snake.It is said that the serpent still inhabits this lake. --I came to drink the water of this lake.It's not immortal, but it's a magical water that enhances energy and recovers from fatigue.Fearfully, I draw the water closer to my mouth.Then I noticed someone standing in front of me.she was a girlWith her long, wet hair, white dress, and big eyes, she seemed to be standing blankly.I thought that there was no way anyone would be in a place like this, but I was so surprised that I couldn't move.And she smiled, or rather, grinned, and hugged me.She almost screamed at the cool feeling, but no sound came out.As she tightens her grip, she slowly steps back into the lake.She looks like she's wrapped around a big snake.She's kind of dangerous, she panicked, but she couldn't move.I can not breathe.Before I knew it, the water was up to her shoulders.It's no good, let's give up.I closed her eyes and surrendered myself to her. ――When I came to my senses, I was standing in the center street of Shibuya.Did you daydream because of the heat?I remember the girl's face very clearly in my dream, but she was a girl I had never met before.I start walking in search of a girl to scout while being confused.I could see running water across the narrow road.The next thing I saw was a girl with long hair, a white dress, and big eyes.Oh, let's call out to this kid.When I decided that, I felt like she was smiling.
