Note:Japanese custom "the second button"
After school graduation ceremony,girls students asks the graduate she loves to give her his second button of his school uniform.And she accepts the button and keeps it never to forget him.
This is a way to convey her love.Some girls confess her love to him at first,and then ask him to give her the button.
Of course not all the girls students do that,but Japanese sometimes take the second button as a symbol of the graduation ceremony, their student days, and their youth.

But... is it any good?
