Ephemeral Spelling With You

Shizuku Hoshikawa, a high school girl who lives avoiding contact with people, writes a novel which is accidentally read by her classmate Kaori Asaka.
She loves it but finds out Hoshikawa wasn't planning to write anymore due to lack of ideas, to which she ends up saying:
"Let's start going out, you and me… You can write a story about our own love."
