You know we're four years apart, right?
"..Uh, but?"
"They say a four-year age difference doesn't even require checking compatibility. Will you go out with me?"
I don't date minors.
I'm 19 years old.
"Still, you're a minor."
"Ha... then what excuse are you going to make next year?"
"..uh?"
"I'll be an adult next year, so how are you going to refuse then?"
"You... you're a younger brother I've known for a long time. I have no reason to see you as a man."
"..Wow, you're really cruel, sis."
"sorry"
"Okay, I'll stop confessing this year."
Don't do it next year either.
"..I'll go. I won't take you home today because I'm annoyed."
"...They say a 4-year age difference is so good you don't even need to check compatibility."
"But what is this... ha"
