The protagonist of this game is a small staff member who works in the government. His father, who has not seen him for many years, accidentally committed suicide. Although he and his father are not familiar with it, the inside story of suicide is like a bottomless wardrobe. The more new clues come out;
His colleagues don’t trust each other, and the boss constantly causes him to do tasks that seem to be very irregular. Those who claim to be his father’s old friends promised to bring him, but never really lend a helping hand. Just tell him how to do it right. But how do you do it right? Who can trust? It depends on the player's choice.
