Deha fanfic
To put it simply, this is a bloody story about Harry and Draco having an affair behind the back of the public, and the arrogant and petite Harry making a "confidentiality agreement" because he was worried about not allowing his loyal dog Draco to reveal the fact of their relationship. Draco-chan, who had been holding it in for a long time, obviously couldn't hold it in any longer.
