What would Swatch be like as a romantic partner?
The absolute best. I'm being biased, I know.
Swatch would be very attentive to your needs.
Yes, he will always serve Queen, no doubt about that, but his lover's needs will always be at the forefront of his mind as well.
If you have a favorite dessert or food item? He will make it swiftly or learn to make it just for you if he's never done so before.
Since he's loyally served Queen for so long and watched over the Swatchlings like they're family, his mannerism are a bit on that side of that spectrum.
He'll ask if there's anything he can do for you.
He'll want to schedule a time—yes, schedule—for cuddling.
Swatch is used to having everything running just so. It'll take a bit of breaking that habit when he's in a relationship.
He won't get upset if you ignore that schedule and cuddle him whenever you wish to, of course. If anything, Swatch will be surprised.
He'll offer to make your bath and bathe you.
If you'd be so bold to allow him to do such a thing, he would compliment every part of your body—be in awe of it.
If you're unwell, he would ask another Swatchling to take his place at the front counter for a moment as he tended to your every need.
Maybe it's because he's a bird monster, but I'd like to think he's a good singer.
Perhaps Swatch sings to you during the evenings to try and help you sleep.
If that doesn't help, he can always read a book to you if you'd like.
The gentle, deep and soothing tone of his voice is quite melodic on its own.
The best part of sleeping for the night is feeling him hold you. His feathers are so warm, especially when he fluffs up.
