I saw the raws and like i thought the black haired was in love with the blond guy's grandfather( they have the same face)...he didn't have a chance to experiment his love...so it's like the blond guy is his replacement...even if they fell in love that black haired chose to return in his time...that was a bit sad but at least he was able to love and being loved.
Hahaha i like the easy going Azuma-kun
