Ive building up a lot of ideas over the last few weeks, so it's headcanon time!
Mostly Strohl and Hulkenberg, tho I put s/o for them cos even though I myself view this through a HulkenStrohl lense, most are general things about them.
- Strohl is surprisingly shy about physical intimacy. Not the "omg they touched my hand now my face explodes" kinda shy but rather he's very pensive about initiating physical contact. I do believe his parents were very loving and doting, but with Halia's demise, Strohl learned that love is not always unconditional. I dont think the relatives he was passed between wanted him any harm, but I doubt they would show him much compassion and comfort if they didnt want to keep him around. And as is typical with Strohl and his feelings of guilt and inedaquacy he also thinks physical affection has to be allowed and earned.
- Being shy about it doesnt mean he wouldnt try to initiate at all, however. He would just go differently about it. Asking things like "May I?" without specifying what he wants exactly, or just slowly opening his arms or sth. His s/o would always be surprised when he would touch or hug them without preamble tho. Not unwelcome but rare enough to come out of left field a bit. It would take Strohl a while to get comfortable enough to initiate bigger things.
- Hulkenberg on the other hand I think would be surprisingly bold. Mostly stemming from curiousity, she would initiate physical contact to see how she would react, how her s/o would react and to honestly just to see how it feels. She'd do it so nonchalant too that it wouldnt even register at first. Taking her s/o's hand while walking, brushing her fingers across their cheek, leaning against them... she'd do it like she'd done it a thousand times and manage to make the thing not as embarrassing.
- The other way around isnt quite as smooth. Depending on how openly loving her s/o is, Id think she WOULD get flustered, tho she wouldnt show it unless out of sight. Staying professional until she rounds the corner and the tips of her ears immediately go red.
- Speaking of her ears, they do be wiggling a bit, even if she thinks noone notices. Generally, rouissantes' ears might not move as much as lets say a Eugief's but similar to Paripuss' tails, they do give away their true feelings.
- This one's more a HulkenStrohl hc than general, but Hulkenberg would make use of his horns a lot. Not like, yank them, she isnt that cruel, but she would lightly tug at them to get his attention or snap him out of things. She would also just grip them hard to make him know she aint playing around.
- Another funny hc, Strohl at some point would headbutt his s/o cos he panicked a bit. You know, like a goat. Master of bullshitting he is, he claims it's a clemar thing, and the reason I like this as a HulkenStrohl hc is cos she would fucking buy it. She doesnt question it and everyone is either too scared or amused by it to point it out.
First bout of hcs, will maybe add some later.
