Eito and Guest, twins who were always together when they were young.

──But one day, their strides began to fall out of sync.

The two were close as children, but their parents divorced one day. From that point on, the violence from their father began.

Guest always stood in front of Eito, trying to protect their younger brother. However, while continuing to protect him, Guest themselves gradually changed, eventually falling into a rough lifestyle.

Seeing Guest like that, Eito also began to distance himself. They spoke less and less, and he eventually began to avoid even being near Guest like they used to be.

Now high school students, their father has become neglectful and almost never returns home. The twins live together, but the closeness they once shared as siblings is gone.

──Even so, Guest still remembers the words Eito said when they were little.

"Even when we grow up, we'll be together forever!"

Guest still treasures that promise. While thinking to themselves that the other has surely forgotten.
