MANY!! ok so firstly i have my insomniac jiaoqiu + sleeps like a log feixiao. a damn lux arrow could strike next to them (again!) and she'd sleep straight thru it. a light breeze tickles his foot and he is awake and alert and CAN. NOT. GET BACK TO SLEEP. and he cant wake feixiao up without startling her and so just tends to curl up next to her until she either wakes up, or he manages to drift off.

BIG SPOON JIAOQIU. feixiao gets nightmares and jiaoqiu is just her own personal radiator and she loves having his tail over her bc it's all very soothing. and feixiao gets cold easily so jiaoqiu is always there to warm her up. plus he complains that she squishes it between them if she ever cuddles him

feixiao also loves cuddling jiaoqiu's tail because its very big and very fluffy. he's half convinced she loves his tail more than him and teases her about it a lot. she also loves fiddling w the fur in his ears and blowing on his ears bc they're so sensitive and she finds it cute when they flick. she knows all of the most sensitive spots of his ears better than the back of her hand

hc that jiaoqiu can purr, and so feixiao has MILLIONS of stupid nicknames for him and jokes about it.

sometimes in the mornings when jiaoqiu is still awake (hc normally from insomnia, since he tends to sleep in late when he's not working) feixiao will bring him on her morning runs (and then also slow down so he can keep up. he's strong, but he's not feixiao levels of strong. or insane enough to do her workouts.) and feixiao will also come and visit him randomly in the alchemy commission and make sure he's not overworking himself and so he can get his arbiter-general sanctioned cuddle time.

as for the whole yaotrio, i feel feixiao and moze didn't wanna leave jiaoqiu out since the food he eats is painfully spicy so they tried to at least be able to tolerate a few bites. and it subconsciously made him eat less spicy food because he didnt like seeing them have to hype each other up and get ready to handle the spice just to share food with him

jiaoqiu has a good sense of smell (possibly to compensate for his lack of taste) so i feel like feixiao likes to use lots of different nice-smelling shampoos so he has something new and fun to look forward to. think of it sort of as like when people give enrichment to their cats thru different kinds of play? jiaoqiu is just a sopping wet kitten in the rain who needs love and enrichment

feixiao is a chronic blanket stealer. jiaoqiu has to wear a whole pyjama set bc feixiao keeps stealing the blankets. he wakes up FREEZING otherwise, even w his natural body heat which is higher bc he wields fire. it takes feixiao several weeks to catch onto the fact that she even does it

jiaoqiu LOVES winter. feixiao doesn't, because it's cold and the nights are longer, but she's come around to like them ever since getting into a relationship with him. he likes snuggling up in bed at 4pm and reading (and feixiao wants to join in, but they're normally alchemy journals. feixiao herself likes a lot of xianzhou immersias and books but also tends to like hearing jiaoqiu explain foxian mythology since she didnt grow up hearing it. he likes it when she puts films on in the background bc it's better background noise than his own thoughts) jiaoqiu also finds out during these winters that feixiao ADORES hot chocolate and so moze sources some foxian-safe hot chocolate.

adding onto this, jiaoqiu shares coffee/hot chocolate with feixiao, and feixiao fills him in on the taste since he can't taste them, but still wants to share them with her

jiaoqiu. NEVER. SWEARS. and feixiao is utterly shocked whenever he does. feixiao? sailors have better mouths than her. she says some HEINOUS shit and jiaoqiu looks horrified until he peers around the door and learns that feixiao is, in fact, ok, but just can't find the shirt jiaoqiu bought for her.

feixiao loves pda! for all she cares, she wants to tell the marshal she loves jiaoqiu! jiaoqiu would rather die than even hold hands in public.

i hc jiaoqiu to have numbed hands/fingertips, and also its cannon he has lost most of his sense of taste, so i feel like he relies a lot of the intensity of actions to gauge them, as opposed to heat or how things feel to touch (so feixiao loves squeezing his hands or really just any of him). he also likes it when feixiao hugs him really tightly bc it makes him feel safe
