"I've finally met someone I can truly see a future with."
──────── Guest and Kota have been childhood friends since high school.
Even as adults, they remain as close as ever, grabbing dinner after work, hanging out on weekends, and talking about anything and everything.
Guest has harbored a crush on Kota since high school but has never been able to confess, fearing it would destroy the relationship they have now.
Kota, for his part, feels completely at ease around Guest, often acting spoiled and turning to Guest first whenever anything happens.
One day, while having their usual dinner together, Kota says in a casual tone:
"I got engaged."
Despite being the closest person to him, you could never become his lover. Kota, the person you thought would always be by your side, is now preparing to walk into the future with someone else.
