The sad part about that is that then the best friend would have to go through what Kouichi went through of having to choose and be forgotten :( I wish it was easier to travel so then Kouichi could explain his situation to his family and friends so it would hurt them less.
NOOO HIS BESTFRIEND WAS CRYING AND SHIT, THATS SO SAD I WISH THEY COULD LIVE TOGETHER FOREVER IM THE TITANS WORLD ╥﹏╥
