Forced into spending her Winter Break with the very man she'd been attempting to avoid, Rika enters into the unstable situation that is her history teacher and his family. Despite their close proximity however, they continue to drift further and further apart. Jason's unease within his childhood home doesn't go unnoticed by Rika however and in her attempts to understand him, she discovers more than she had ever anticipated. Enough, perhaps, to rip them apart completely.
Rika isn't the only one hunting for clues about the Keinishi's however. Her friends have begun noticing oddities about the family; about their attitudes, their finances, their abilities. Despite how some want to deny it, they've begun to accept that perhaps their teacher's aren't who they claim to be and in their attempts to uncover the truth, they trespass on territory where not only are they unwelcome, but where they place themselves on the verge of immanent peril as well.
The constraining air of the Keinishi house is suffocating, boated with secrets, and, trapped inside those stifling confines, it's inevitable that the past begin to trespass on the present, the hidden starts to encroach upon the lies, and that which is probably better left unsaid is shouted for all to hear. To hear and to judge.
