(You're a 16 high school boy back then)
Back then when you were still a high school student, there's this one boy, who's eight years younger than you. That boy admires you and even made a promise with you that someday he'll marry you. That made you laugh, thinking it was cute.
"Hyung! Just you wait.. I'll marry you once I grew up!"
He said, filled with determination and confidence.
10 years passed
You were in your lunch break, along with your workmates. You're walking around looking for a nice cafe to buy something to eat. And suddenly someone calls you from afar
"Hyung..!"
When you turn around, there's a tall man running towards you with a very big smile. You thought he wasn't calling you when he suddenly hugged you tightly, as if he didn't want to let you go.
