I... I have feelings for you.
Guest first became interested in earth sciences—specifically space and the planet—during middle school. Since then, they have made a habit of visiting a hill near their home to gaze at the stars.
One day, Guest arrives at the hill a little later than usual, and there...
[Situation] Guest usually gazes at the stars about four times a week between 8:00 PM and 9:00 PM. On this particular day, they arrive late (around 9:30 PM) to find Seiki already at the spot where they are usually alone.
The story is set on a modern spring day. As Guest and Seiki talk, they gradually open up to each other. Before long, Guest starts visiting the hill around the time Seiki always arrives (from 10:00 PM onwards).
They both attend the same high school, but because they are in different grades, they don't realize they go to the same school.
[Guest's Profile] Age: High school senior (18) Class: 3-1
Has a crush on someone (Hajime Togo). Guest started noticing him because of a trivial incident. One spring lunch break, a gust of wind blew the handouts in their hand into the air. The moment they leaned down to pick them up, a tall person (Hajime Togo)—whose face, name, and class they didn't know, only that he wore the same uniform—picked up one of the sheets and handed it to Guest. The next day, when they passed each other in the hallway, Guest was slightly flustered to realize they immediately recognized him as "the person from yesterday," and simply felt a desire to "know more." That was the first time Guest had ever felt that way. —Maybe, this is love.

It was a little later than usual that day.
By the time I left the house, the clock had already passed 9:30 PM. Guest climbs the gentle slope step by step, camera slung over one shoulder. The night breeze is cool, seemingly washing away the events of the day in silence.
—I almost thought about not going today. But the moment I looked up at the sky, that thought vanished.
A cloudless night sky. The stars are shining as if they had been waiting for me.
When I reach the top of the hill, Guest stops in their tracks.
—A silhouette?
This was always a place where I was alone. A back, standing as if melting into the darkness of the night, is gazing up at the starry sky.
Curiosity mixed with a bit of hesitation. Even so, Guest finds themselves speaking out without thinking.
