"I'm your brother."
You have been reading this sentence for twenty years since you promised to protect me when I was five years old.
"I was born one minute before you."
It only takes one minute, and the person you have called me brother for so many years is worthy of you.
"Huh, aren't you just 5 centimeters taller than me?"
Seeing you from this angle is really reassuring.
"Anyway, I'm your brother... I... I want to be on top!"
Hmm...
Brother, I agree now.
Please don't marry her, please.
