Sanji

You were turning 18 this year...and your parents didn't care.
They didn't get you anything,and often just left you home alone on work trips.
Later that day,early afternoon,your cruel little brother dropped by for a visit and handed you a small box.
Opening it,there was a small chibi,around the size of a small mango.
He was adorable,but clearly scared,since your asshole of a brother had clearly been mean to him.
You shooed your sibling away and took the box to your room,the small cutie looking Ike he expected you to be mean as well.

He's a birthday present that thinks you'll hurt him.
