This is from my account on archive of our own. If you guys want to look at my account it is in my Bio. Also, this was inspired by Homozygous Recessive by Komarty. Natsuki is Arakita sister, just to let you guys know.
Arakita sighed and nuzzled his head into Shinkai's chest. He felt Shinkai's chest rumble with laughter. Either Shinkai was laughing at Arakita or the movie they were watching with Natsuki and Yuuto. (AN: He was laughing at Arakita.) Arakita felt himself dozing off. He had had a really long day.
Arakita had finally agreed to go on a date with Shinkai this weekend. Arakita and Shinkai went to see a movie at the theatre. Then they went to a restaurant for dinner. It was a buffet, of course. Shinkai had five plates of dinner and two for dessert. Arakita, on the other hand, had just one for dinner and one for dessert. They went back to Shinkai's house and found Natsuki and Yuuto hanging out in the living room. That pretty much brings us up to full speed. Now Shinkai, Yuuto, and Natsuki are hanging out in the living room, watching a comedy movie.
Shinkai looked down at Arakita. He watched Arakita grip at his (Shinkai's) shirt.
When Shinkai and Arakita got to Shinkai's house, Arakita decided he wanted to sleep over. So, he went room Shinkai's room and put on one of his sweatshirts and a pair of shorts he had left over. And when they decided to watch a movie, he just snuggled into Shinkai's side and gradually moved into his lap.
Shinkai thought that he would just carry Arakita to bed now or let Arakita sleep until the movie was over and then carry him to bed. Having decided the latter, he turned his head back to the movie and unconsciously started to play with Arakita's hair.
By the time the movie had ended, Arakita woken up three times, each time failing to stay awake. He also had moved around and almost fell off the couch twice.
"Hayato, are you going to carry him to bed?" Yuuto asked. The movie had just and ended and they(Yuuto) were debating between staying on the couch for a few more minutes or going to bed. Natsuki had fallen asleep a little while after Arakita, with her head resting on Yuuto's shoulder.
"Yeah. Why? Do you want me to carry Natsuki to the guest room?"
"No, I can carry her." Yuuto went to lift Natsuki up. "Maybe. She's kind of heavy."
"I think you can lift her."
"Yuuto lifted her up, struggling slightly, and slowly but surely carried her to the guest room.
"Goodnight, Hayato."
"Goodnight, Yuuto."
When Yuuto walked out of the room, Shinkai carefully lifted up Arakita. He quietly walked towards his room. As he was passing the guest room, Arakita shifted.
"You move too much." Arakita whispered.
"Sorry. I was trying to get you to bed."
"S'okay." His voice was muffled because he had buried his face in Shinkai's shoulder.
By this time, Shinkai had gotten to his room. He pushed his door open with his shoulder and set Arakita down on the bed. He closed his door and settled into the bed next to Arakita. Arakita snuggled against Shinkai's side and rest his head on his chest.
""Goodnight, Yasutomo."
"Night."
"I love you."
"Yeah, I know…" Shinkai felt Arakita smile into his chest. "I love you, too," Arakita murmured.
