i own nothing of this video, it all belongs to it rightfull owner!
it only for others enjoyment. i'll be uploading more for others out there who love Hetalia MMD.
while watching this with a friend of main, i said "i love to have that as my birthday cake"", "i was going to say that" she repiled. but wouldn't you?
