Why the 2nd button?
Because it is closest to the heart. They say the 2nd button contains memories and feelings he kept throughout these years. Receiving a 2nd button means he wants you to remember him and understand his feelings. The girl can also ask for the 2nd button from the guy that she likes.
I find this really cute! I can imagine how nerve racking it is on the day. I sometimes wish we did that over here in England. It would be interesting to see how many buttons I'd get, if any. I do find it really adorable!
Why is Japan so cute?!
