He would never tell her this, but Rin has always been small and cute.
It goes all the way back when they were kids: while Obito was a spastic mess of nervous energy, Rin was cheerful and calm, giggling good-naturedly at his antics while their classmates were understandably irritated. Her hands were small; he remembers how her fingers tapered delicately as they gently touched his wrist. She had large brown eyes that made his breath catch when they met his, and her mouth was always in a small smile, her lips curled up at the corners.
She's so much smaller than him. Even as an adult, she barely comes up to his chest, and when she kisses him he has to bend down, meet her halfway while she pushes up on her toes to reach him. His fingers can curl over the tops of her hands and the whole breadth of her body can fit across the width of his torso. "I could put you in my pocket," he said once, and Rin just laughed at him.
She's pregnant now, short and round and waddling, and somehow she looks just comically cute. Like a little pokemon pikachu-type animal, just soft and fluffy and squishy looking. She's always been the calmer one, good-natured and cheerful, but seeing her get flustered, bursting into tears because she stepped on a flower or asking him to Kamui her to the mini mart because even though it's midnight she's hungry again - it's ridiculously, stupidly, incredibly cute. She's like a clumsy puppy and it makes him smile just thinking about it.
"Which one of you assholes threw that at him?!" Rin says, after someone had clocked Obito in the face with a rotten egg, and Kakashi and Obito look on in horror as Rin lunges toward the heckler, a little butterball of rage and fury.
And Obito is struck with the realization that Rin loves him so much, she'd jump into an audience of angry nin and kick the ass of anyone who'd insult him, despite the fact that she's heavily pregnant.
"Sorry," Rin says. Her eyes close into cute little crescents. "The pregnancy hormones make me kind of crazy."
And he feels a happy warmth settle at the seat of his chest, because Nohara Rin really loves him.
