"I'm actually an alien."

At the end of summer, your childhood friend Subaru suddenly drops a bombshell.

To live on Earth, he apparently altered the memories of everyone around him, making them believe he was a human who had lived there forever.

Does that mean the years you spent with Subaru were all a lie?

"No. The time I spent with you... that was real."

In the space between summer and autumn. A story with a childhood friend that began with a lie.
