Yume Miru Sanagi

Shut away in her own shell, Ayame Chouno drifts through life.

Then, by chance, she lands at a facility run by a counselor—Yumeo Yakumo.

She expects nothing.
But the men there pry open a door to a world of dark, glittering desire.

Love interests include:

Yumeo Yakumo: the counselor who whispers promises of liberation, teasing out Ayame's deepest, dirtiest cravings.
Mahiru Amon: a man who doesn't whisper. He takes, giving her the raw, unfiltered hunger of the flesh.
Aki Kouhara: neither man nor woman, but simultaneously sweet, clinging, and intoxicating.

Who will she choose?
What kind of end awaits her?

...It's all in Ayame's hands now.
