Origin Date Unknown. However, it was around my Aphmau phase, which dates it at least two years ago.

Vylad and Dante have a promise that Vylad will never have to wake up alone. Dante gets drugged one night and Vylad catches him being kissed, running to Aphmau crying. Dante then makes an agreement with Garroth (who approached him very aggressively) that someone is always there when Vylad wakes up. A couple weeks pass and Dante wakes up to Vylad curling into his side in his bed.

Bold is Dante
Italics is Vylad
Bold and Italics is Both

They woke up next to each other.
Dante smiled at the younger.
Vylad curled farther into Dante's chest.
