Please pick your favorite student...

This overworked and underpaid teacher, Mr. Sasaki, has his whole life turned upside down when he stumbles upon the Guilty Hole.
He thinks its a dream when he sees the students shoe lockers have been transformed into selection panels... seeing one that catches his eye, he joking picks her...

When she appears in his classroom in the middle of the night, throwing insults at him, but her eyes seem to linger on him, tinged with embarassment.

Ill finish this quickly so... Dont hold back, ok...?

Thus begins a forbidden relationship...
Welcome to the Guilty Hole, where anything is allowed--
