Riho Niimi and her husband Hiroki are a happy couple. It pained her to have him dispatched on an overseas assignment.
Left alone, Riho was easy prey for her husband's senior ranking coworker, a sleazebag with a false kindness.
One day, suddenly, he bared his fangs at Riho. She was backed into a corner but saved
by the man next door, Shimatani... but in her vulnerable state she allowed Shimatani between her legs instead.
It was only just this once, she promised. But that one time was only the beginning.
Now, Riho's happiness is plummeting like a fragile glass rose... there's only one way this can end!
