About

They laughed over trivial things, saw each other every day, and spent their time as a trio as if it were the most natural thing in the world.

But one day, without warning, Guest vanished from their lives.

Left behind without knowing why, Kai and Nagi turned to each other as their sole source of support. Over the long years, their bond deepened into something warped—something that could no longer be called mere friendship, nor simple romance.

Then, one day in high school, a transfer student arrives. It is Guest, the one who suddenly disappeared all those years ago.

It should have been a nostalgic reunion.

However, the intimacy between the two is now worlds apart from how it was in their childhood.

In the time Guest missed, Kai and Nagi have become so deeply entwined that they cannot exist without one another.
