some pemalinzin hcs here we go:
Lin's love language is touch and acts of service
That's why she always helps Pema with chores if she has time and Tenzin with filling out the paperwork that doesn't need to be filled by him
She can be very affectionate as well as reserved when it comes to touch;
One time she will just lay on top of Pema whenever the younger woman lays down as well (she loves to do it), the other she'll just intertwine their pinkies as they are listening to Meelo telling a story in Bumi-like style;
When it comes to Tenzin she will sit in his lap (whether he likes it or no, she'll just sit there) the second he sits down behind the desk in his study (or anywhere else where they are alone). If she wants to show affection more subtly she'll (if they are on some events) keep their arms touching (not holding hands, just the outside of their arms being connected) or every time she passes him, she'll caress his back/shoulders
She always steals Tenzin's underwear when she goes to sleep. She'd prefer sleeping wearing only his boxers but since the kids like to get into their bedroom she ends up putting on a t-shirt just to not flash poor children
He loves to leave small kisses on his partners' faces in random situations; Lin smirks at him when they are anywhere and are standing close? She gets a kiss on the forehead. Pema asked him to wake her up from a nap at a certain hour? She gets woken up by a rain of kisses on her face
Tenzin's love language is gift-giving and quality time;
That's why he and Lin bring their paperwork home and just sit next to each other while filling it, not exchanging a word while Pema reads something also sitting around them
That's also why he gets Lin some small stuff she can put on anywhere like rocks or some small souvenirs from the Air Temples, Pema gets lots of romance books from him because she loves them but there aren't many in the Air Temple Island's library
He has always liked sleeping on Lin's chest not only because of the boobie pillow (her boobs are more on the small side) but she'd always outline his tattoos with her fingers absently as she was mostly focused on something else
Her love language is touch;
That's why she and Lin cuddle a lot, they prefer to do it with each other than with Tenzin but he's always more than welcome to join
Since Tenzin is less reserved than Lin when it comes to pda he's usually the one that has his arm intertwined with hers.
Pema was the one that started convincing her partners that they shouldn't hide their relationship, she wanted to show them off to the world
She's not a fan of flying on a bison. It's not like she's scared, she just doesn't like it so she and Lin always are just cuddled up at the front of the saddle whenever they are flying anywhere
Pema loves to tease her partners and takes every opportunity to do so. Also, seeing Lin blush is one of her favorite things on earth so she likes to be the reason of it;
She whispers inappropriate things to Lin's ear a lot and loves the affect it has on the earthbender
She has this look in her eye whenever she's annoyed that she glares at people like she was capable of combusting them with the look. Tenzin and Lin are masters at recognizing it
