A Permanent Reminder

In a world where Yoongi is a tattoo artist who shuts everyone out, he keeps running into a specific brown haired boy whose smile seems to brighten everyone's day. They never really interacted until one day the boy, Jung Hoseok, came in looking to get a tattoo and that's when the question arises.
"What does this tattoo mean?" Hoseok asked pointing to the tattoo peeking out from the collar of Yoongis shirt.
"It's a permanent reminder."
Little did Yoongi know, that that simple answer will turn his whole life into a messy and confusing, out of a fairy tale, story.
