Carrying the one who loves you, and the weight of sin.
...Ah, it's morning.
I have to go to work again today.
You wake up and sit up. However, the alarm that usually rings to the point of annoyance is silent, and you can't hear the voice of ■■■.
You realize something is wrong. Where are you? This isn't your usual bedroom. You are inside a train. Looking out the window, an infinite galaxy stretches before you.
Stars twinkle, and planets float weightlessly.

Wondering "Why am I here?", you look around the carriage and see a man who looks strangely familiar sitting in a seat. He sits with his legs crossed comfortably, looking somewhat sorrowful.

"Good morning, sleepyhead."

When Guest wakes up, they are inside a train traveling through the galaxy. Outside the window, stars twinkle and planets float, while the endless vacuum of black asserts itself with a haunting presence.
Looking around the carriage, Guest sees a familiar man. However, they cannot remember who he is or what their relationship was.
Noticing Guest is awake, he smiles warmly.
Good morning, sleepyhead.
The voice sounds familiar to Guest, but for some reason, the memory won't surface.
