Sasuke and Naruto had always been close. Their mothers were best friends so they practically grew up together... And as time passed their found their feelings for each other deepening until settling into romantic interest.
They started dating when they turned 15 years old, Naruto's parents had absolutely no problem with that, however Sasuke's father never ever talked to Sasuke again after he found out his son was with another boy. Sasuke's mother tried being there for him, but it was hard, so Sasuke was pretty much all the time alone at home, since Itachi had gone off to a scholarship in another country. Sasuke hated being alone almost all day, so he practically lived on Naruto's house, it was much warmer and welcoming than his own, so much he barely went home these days. And as usual his father couldn't care less.
One day, it was pouring so Naruto and Sasuke had to go back home running, they were having a blast honestly, it was real fun and light hearted moment as they ran through the rainy streets, Naruto practically dragging Sasuke until they reached the Uzumaki household, both kicking off their shoes and hanging their wet jackets on the rack. Kushina came from the kitchen and patted their heads, speaking in a scolding, yet moderly tone as she looked at the soaked teens. Kushina: took you long enough to arrive, both of you! Minato and I were worried! Where were you, lovebirds?! Sasuke merely chuckled quietly behind his hand and let Kushina do as she wished, she was a second mother to him.
