Asahi Azumane x Reader- Dog Queen

[y/n] was always small. No matter what size she actually was, something about her just gave off a smaller feeling than most people. It did not help that [y/n] did not have as large an interest in small things than she did in big things. Her clothes were always over-sized, her significant others were always either wider or taller or just generally physically bigger than her, she always turned in the biggest reports in the class, she always used way-too-long words, her bed was a California King size, she specifically bought a 2DS XL because it was much larger than a normal 3DS... She just loved larger things. This interest especially applied to the easiest large animals she could get: dogs.
"Asahi-kun, what kind of dogs do you like?" [y/n] asked, smiling at him widely as she walked beside him.
"I guess smaller, non-threatening ones. Are there any that don't bite?" He replied, tilting his head. He realized that she was not listening to him at all.
"Yeah-yeah, whatever. Have you ever seen Great Danes? On their hind legs, they can be over 213.36 centimeters tall." He looked down at the girl nervously as her eyes shone brightly. A dog like that must be aggressive.
"Do you have one of them?" The girl nodded, making him freeze.
"Ah, do you wanna come over today?" She asked, nudging him with her shoulder.The scruffy looking boy did not know how to reply. He did have a crush on her and this could be his chance, but he didn't know if he could be around such a monstrously sized animal without getting unbelievably frightened. The girl thought for a minute, furrowing her eyebrows. "Hmm... Oh, I know! 'll make you something to eat, okay?" The boy nodded, keeping in a sigh of defeat.
"Yeah, sure." During the walk to the girl's house, he constantly debated over whether to grab her hand or not. However, when the girl's hand brushed against his, his face went red; he couldn't be gladder that she was too excited to get home to her dog to realize it. As soon as he entered the house with her, he heard something jingling that got closer and was followed by heavy footfalls. He flinched and nearly yelped as the big dog jumped on the small girl's shoulders, towering over her.
"Hello, my baby!" She greeted in a slightly high-pitched voice, rubbing the large dog's cheeks. She lightly grabbed the dog's paws off her shoulders and set them back down, leaning down the kiss the dog's ears. The dog saw the large teenager and sniffed him nervously, both of them flinching as they moved. The girl, meanwhile, removed her shoes. "Asahi-kun, what should I make you to eat?" She questioned, tapping his forearm. Right, he'd forgotten about that.
"If it's no trouble..."
"It's not!"
"O-okay. Tonkotsu ramen then." The girl nodded, leading the boy to the living room before heading to the kitchen. He waited at the kotatsu, nervously looking at the large dog who stared at him straight on. Oh, god, did it want to eat him?
"Asahi-kun, it's done!" The girl announced, the dog walking away carefully and avoiding her feet. She put the bowl in front of him, he nervously looking at the dog who sat at the table to his right and to the left of the girl. "Ah, I think he likes you, Asahi-kun." She smiled. He looked up from his food, noodles still hanging from his mouth. She pointed at the dog next to them, making him realize just how much its tail was wagging; oh, was that what that thumping sound was? "Aha, you're both really cute!" He nearly choked on his food, the girl still going on with her thoughts. "Ah, I probably have a lot of competition, huh? Okay! Asahi-kun! If you're okay with it, you're mine from now on, okay?" His face went red, nodding as he tried to avoid choking to death on his favorite food. "Yay!" He could most definitely put up with an intimidating dog for this.
