Quackity's a workaholic.
He would spend nights working instead of sleeping, but eventually, when Las Nevadas was developed enough to mostly run itself, that it isn't just work. He could never truly sleep, never wanted to fall asleep, scared of his own mind when not focused on something, only sometimes pushing himself to rest through alcohol or pure exhaustion.
Wilbur on the other hand never had issues falling asleep. It came to him naturally, or maybe it was the constant exhaustion (especially after revival). He could never really sleep though. He would fall asleep, but not rest, half conscious most of the time, or experiencing terrible nightmares and waking up in the middle of the night.
Inspired by your recent art, Quackity would sometimes just stare at sleeping Wilbur. But, Wilbur would often stare at sleeping Quackity in the morning, admiring his lover when he's all soft and calm, and thinking of ways to surprise him with something nice when he wakes up. Maybe he should make him breakfast.
Ok so I love this cause I absolutely adore the "opposites attract" HCs with Q but it'd always be like "well they both definitely have sleep issues" but this is a way to have both and like that's a major slay
Three little hcs regarding their sleeping habits: 1. they both have a tendency to wake up when the other does, just automatically - they're just synchronised (most of the time at least one of them falls right back asleep tho); 2. Wilbur's weak sleep is significantly worse when Quackity's still working - like, he will finally come to bed and Wil's asleep but then Q sits down on the bed (quietly as fuck) and Wilbur's like "hey"; 3. they switch around their sleeping positions, but Wilbur absolutely loves being the small spoon - partly cause he's always cold, but mainly cause he wasn't held enough as a kid/hj
Aaaand in the spirit of the ask, a little headcanon that's tied up with this (plus more at the end):
Common one, but I'll elaborate - Quackity's warm, Wilbur's cold. So, of course Wilbur's cold after revival cause his body's kinda fucked up and all that. Quackity - for a normal human (or a normal animal hybrid I guess idk works with duck too) consistently has a pretty high body temperature. He prefers sleeping mostly undressed (maybe with shorts on but that's not a guarantee/lh), he usually has to unbutton his shirt a bit lower than standard (I mean he's also a whore but it's a 2 in 1 y'know), etc etc.
Now, with Schlatt that resulted in limited cuddling even in the honeymoon phase cause the other also had a higher body temperature, and they'd just end up sweaty and uncomfortable.
With Eret the relationship started with a generic, platonic, positive message ("you matter ♡ -Eret" which they gave out to people in general just as a nice gesture, but nothing romantic) and ended with Q alone at the altar, so it's probably safe to say that didn't really come up.
With Karl and Sapnap though his body temperature was both too much, and not enough - Sapnap, as a demon hybrid, was much warmer, so with him cuddling wasn't really the most comfortable long-term, and while Karl was slightly on the colder side, Quackity wasn't as warm as Sapnap, so Karl would mostly cling to the latter. They'd try to make it all "even", but the emotional and physical distance was still noticeable.
And then there's Wilbur.
In pogtopia they didn't really cuddle much, but whenever they touched shoulders or leaned against each other Quackity noticed that Wilbur would frequently lean in for just a second longer than normal. This came back 10x stronger after revival. With a lot of Wilbur's nerves and blood vessels fucked up, he's pretty cold most of the time. The first time they cuddle he absolutely sinks into the embrace, making a comment about how nicely warm the other is. Quackity doesn't expect it to hit him as hard as it does. He giggles, slightly flustered, and dismisses it as Wilbur just being colder. From then on it repeats, and soon enough Quackity returns the favour by unintentionally hitting Wilbur with something along the lines of "you're like, the perfect temperature". See, Wilbur's always been on the colder side. He'd hear comments about how cold his hands were - not to even mention post revival - and he never really thought much of it, until Quackity's comment just hit him like a ton of bricks, and he just felt so perfectly in place in Q's arms. They just form the perfect temperature equilibrium; not too warm, not too cold - just perfect.
Little bonus: Quackity starts occasionally taking a jacket or sth with him even though he doesn't need it but he knows Wilbur will probably get cold (and need a second jacket).
Another little bonus that connects this HC to a different one about Quackity having sensory issues. VERY tldr is that sometimes he just gets this intense physical discomfort in his limbs (AuADHD moment), and only way to lessen it is intense stretching, OOOORR using Wilbur as his personal ice bag. There'll be nights where Wilbur will try to move his foot cause "it's probably too cold and bothering Q" just for Quackity to "scold" him for moving it cause it was pressing perfectly into his calf and keeping him from losing his mind cause of sensory issues.
Also they both have food sensitivities, but Q's are more broad, and sometimes they'll spend hours arguing(/lovingly) over what to get on pizza, or when they go to a new food place sometimes Wilbur will just look at Quackity who's staring at the idk olives he accidentally ordered in his food (cause he didn't know the dish contained them) and he will just silently slide over his plate so that his boyfriend can peacefully pick all of them out and give them to Wilbur. When Wilbur encounters food sensitivities - say, in a restaurant - Quackity will go full Karen mode and make sure his boyfriend gets only the food he wants.
Continuing the topic of mental health, sometimes Wilbur will struggle with hygiene during depressive episodes, to which Quackity will either motivate him with showering together(/nsx), a shared bath, if he's doing worse, or in the worst case scenario he'll help him clean himself up with a damp cloth (no judgement, no comments even, just love and support)
