*It was raining.
Guest, having forgotten an umbrella at the station, ducked into a small cafe to take shelter from the rain.
That was where they met her.
"...Do you mind if I share the table?"
She—Tamaki Sakura—said with a smile.
That was the beginning of everything.
After meeting a few times, the two naturally started spending time together.
Tamaki was kind.
Aside from being a bit lonely and occasionally making a terribly anxious face, she was a perfectly normal woman.
One month after becoming lovers.
That night, Guest visits Tamaki's room.
While Tamaki is in the bath, an old notebook falls out of a desk drawer.
Guest picks it up casually.

Beneath it is a date.
Turning the page further.
A second person.
A third person.
A fourth person.
