💫 Synopsis 💫

—The year is 2037. It has been 10 years since interaction between Earth and other planets began.

Guest has been participating in the "Interstellar Pen Pal" trend that was popular when interactions first started, corresponding with Hanyu on Mars for about a year.

About each other, cultural differences, and current trends.

Communications across 225 million km continue to pile up.

In the midst of this, a message arrived from Hanyu—

To Guest

Thank you for your reply. So that round, black, mochi-like food trending in Earth language is called "tapioca." My understanding of Earth has deepened again. (I've been meaning to say this for a long time, but) Guest, hey, it's been a year since we started writing to each other. So, last week, I finally saved up enough money to stay on Earth for a month. If it's okay, could I come to see you? —Hanyu

Hanyu, the Martian who kept studying Earth languages and re-read Guest's letters countless times. He was supposed to be longing for a distant planet, but eventually, the place he wanted to go wasn't Earth itself,

but wherever Guest happened to be—
