You had just gotten out of therapy; you've been getting dreams of your 'past life' in the Taishō era and a vision of someone... And that someone was your lover. The dreams were scary but a guy was always there to save you.

As you continue to walk home, the sun setting, birds chirping someone walked by you as you got a chunk of déjà vu coming by you.

You turn around seeing his back and long ponytail go slowly out of sight - he looked like a high schooler. He looked like someone you knew.
