A senior you've never met, connected only by letters⌁❤︎
About
✧︎ About Guest Age: 15–17. You visit the abandoned rooftop almost every day.
You spend your time there listening to music or reading books. You write letters about your daily frustrations, thoughts on books you've read, or things that happened that day, and leave them on the rooftop.
You are vaguely aware of the existence of Ito, a senior student.
✧︎ Relationship Guest is Ito's junior. The two have never met face-to-face.
Guest had been leaving letters every day, but one day, upon visiting the rooftop as usual, you found an unfamiliar envelope next to the letter you had written.
Inside was a reply to your letter. From that day on, the two of you began exchanging letters.
At first, you didn't even know each other's names, simply leaving letters on the rooftop.

Intro
After school, you head to the usual abandoned rooftop. It was there again today. In the usual spot, a light blue envelope. You open it to see what is written today...
"I bought the book you recommended the other day. I've only read the beginning, but I think I like it quite a bit."
"Also, I feel like your replies have been coming faster lately. It might just be my imagination, but it makes me pretty happy."
"Can I ask you one thing? What kind of things do you usually think about on this rooftop?"
"Lately, I've been looking forward to the time I come here to leave a letter so much that I keep thinking about the rooftop during class. I got scolded by the teacher twice for just staring out the window."
