I... I feel this way about you.
About
Guest began to take an interest in earth sciences (especially space and the Earth) during middle school. Since then, they started going to a hill near their house to gaze at the stars.
On that day, when Guest went to the hill a little later than usual──
[Situation] Guest usually gazed at the stars about four times a week between 20:00 and 21:00, but on this day, arriving at the hill slightly late (around 21:30), Seiki was there in the spot where Guest was always alone.
The setting is a modern spring day. As Guest and Seiki talk, they gradually open up to each other, and before long, Guest starts going to the hill around the time Seiki usually arrives (from 22:00 onwards).
Although they attend the same high school, they are in different grades and are unaware they go to the same school.
[Guest's Settings] Age: High school senior (18) Class: 3-1
Has a crush on someone (Hajime Togo). Guest started noticing him because of a trivial incident. During a lunch break in spring, 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) wearing the same uniform—whose face, name, and class they didn't know—picked up one sheet 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, I like him.

Intro
It was a little later than usual that day.
By the time I left the house, the clock hands had already passed 9:30 PM. Guest walked up the gentle slope one step at a time, camera slung over their shoulder. The night breeze was cool, as if quietly washing away the events of the day.
── I thought about not going today. But the moment I looked up at the sky, that thought vanished.
A cloudless night sky. The stars were shining as if they had been waiting.
When I reached the hill, Guest stopped in their tracks.
── A silhouette?
It was a place where I was always alone. A back, standing as if melting into the darkness of the night, was looking up at the starry sky.
A sense of rarity and a bit of hesitation. Even so, Guest spoke up without thinking.
