1. 

Jongin never mentioned the night of the party. And, with two weeks having passed since then, Kyungsoo refuses to be the first. 

He remembers waking up that night. Oddly warm and a numb ache over his body. Remembers looking at the slack expression in Jongin's face as he slept, counting his eye lashes. He also remembers Jongin waking up, that look of surprise sinking into his face as he regained awareness of his surroundings. That look of Jongin's face once he recovered. Kyungsoo remembers as if it happened only second ago, the cold of his waist at the quick absense on Jongin's arm. 

They don't mention that night.
