A = Affection(How affectionate are they with a s/o?)
Folykl: not affectionate in the traditional sense of the word. She does like to prod you and cling to him and generally try to irritate him for the laughs. Not big on hugs and kisses; tends to feel stifled if she can’t dictate her own range of movement.
Kuprum: he can be subtly affectionate. Likes to flick her, tug on her, things that simultaneously get Folykl’s attention and provide him that subtle skin-to-skin. He also has no concept of personal space; he’s not afraid to cram up shoulder to shoulder with anyone.
F = Fear(What do they do if their s/o is scared? How do they handle it?)
Like either of them would just admit they were scared. There’s a lot of subtle things they notice about the other, though. Kuprum tends to be better at slipping in words that could almost be described as encouraging or hopeful, while Folykl is generally better and distracting you away from the issue at large.
T = Trust(How much do they trust their s/o?)
Trust is super important to both of them; because of Folykl’s condition, every relationship they’d enter could literally be life or death for her. They trust each other implicitly and will generally default to the other’s judgement in times of uncertainty.
W = Wild Card(Get a random domestic headcanon of the character of your choice)
Folykl: sometimes she’ll find something cool that got stuck in her hair and if it won’t stick to her lusus, she’ll stick it to Kuprum (i.e. he’ll pretend not to notice but use his latent static electricity to keep it there).
Kuprum: likes to physically stim using her long sleeves (she lets him chew on them sometimes) or by bouncing her around on his backpack a little. (I cast ADHD on Kuprum).
