THIS MIGHT BE A SPOILER!
It was never stated that they died together. It was strongly implied whit the explosion reaction to the earthquake and the whole coalmining business. The reaction to walking in basement of the shrine and them not being able to see each other because it was dark at the end probably means the mine exploded or collapsed and the two of them died.
ohhhhhhhhhhhh NOW I KNOW
when was it stated that both of their past selves died together?? someone please explain it to me like a 5 year year old ╥﹏╥
