It's Christmas day and Sabito decorated Giyuu's room as a prank but that just ended with Giyuu and Sabito staring at each other then Giyuu decided to pass out onto the bed. Sabito joined him, that was Christmas eve. They wake up the next day and it's Christmas!!!! Sabito loves Giyuu, hates everyone else, sabito is very cold and short tempered but the exact opposite around Giyuu, he also gets jealous easily :( them sleeping in the same bed isn't unusual just not very often. Sabito is a demon.
