Oh, and don't be fooled by the title, it's really not an unrequited angst-fest Mockery
As Harry stepped through the big wooden door - bound with iron today, Draco must be feeling defensive - he could have sworn he felt his stress floating away.
This was his safe retreat, where he and Draco came to be together and release all of the tension they had to hold on to for appearance's sake.
Here, where Draco was already waiting for him, they could while away a few hours not talking or thinking about the war and its effects on both their lives.
Outside, they kept up their taunts, threats and mockery, but in here they would never fight.
