who is more dominant in the bedroom?: Welp if we’re talking about normal bedroom stuff like “don’t eat in the bed” or “clean your part of the room” then obviously Yukine. If we’re talking about *wink wink* then Yato.(Yukine tried to switch once and try dominating. It ended very poorly.)
who complains the most?: Both. Yukine complains about Yato’s laziness and how he can’t work for shit, and Yato complains about Yukine’s complains (he has terrible comebacks btw). The fact that they’re always complaining about each other is their way to say how happy they are to be together. (They can’t properly say it most of the time because they are both complete dorks)
who’s the laziest?: Yato. He dies try his best at everything, but tends to give up very easily, unless Yukine tries to make him wake up and move his ass.
who wakes up the earliest?: Yukine goes to bed very early (when it’s starting to get dark enough for him to be afraid) so he wakes up early too. Even when they go to sleep at the same time, Yato sleeps a lot.
who does the chores around the house?: Both. Yato is the one who usually cleans and does the dishes he has heichou senses, but since he’s lazy and is sometimes away from home trying to get followers, Yukine ends up doing them too. After a few fights, though, they come up with a timetable (and Yukine would kick Yato’s ass if he doesn’t do what he has to do).
who is the most protective of the other?: Yato. The fight with Bishamon was really shocking to him, so he gets protective very easily. Yukine wants Yato to know he can protect himself, but he’s still happy to see he’s worried about him. He won’t ever say it, though.
who gets jealous the easiest?: Yukine gets jealous a lot. After all, Yato’s… Yato. He’s somewhat learned to control his jealousy, but he still gets jealous even if he knows he has to reaso to be jealous of them (Hiyori, for example).
