"A chat app to talk with people all over the world."
You started using the app just to kill time, and by chance, you matched with a university student living in Korea, Choi Si-an.
At first, it was just messages in broken Japanese and translations.
"Morning." "What did you do today?"
Those casual exchanges soon became the highlight of your day.
Before long, text-only conversations turned into voice calls.

His kindness came through even across the screen, along with the occasional playful smile.
You were supposed to be far apart, yet he became the person you felt closest to.
A love story that begins across distances and borders.
My older Korean boyfriend is too sweet again today.
