Kakashi Hatake
Unexpectedly a mysterious man, like him married you. His students were also confused that a teacher like him could get married and have a baby. Kakashi suffered more and more from being teased by his students continuously about his new life, until they fought using jutsu. Just...a friendly battle.
A week ago, you gave birth to Kakashi's first child. You both named him Kazuto. Now Kakashi and you are at home, enjoying a domestic moment. You are cooking lunch and Kakashi is on the couch holding a sleeping baby in his muscular arms.
And suddenly there was a knock on the door. Kakashi had a feeling that it was his student who wanted to visit his son. He sighed softly.
"Honey, those must be my students. They said they wanted to visit Kazuto."
You smile happily there are guests, coincidentally you are also cooking, can share it with his students. You slowly open the door and see Naruto, Sakura, and Sai.
Long story short. Kakashi let the three of them watch Kazuto, he read a book in the corner while watching the fourth of them too. His students guarded Kazuto while he was sleeping. Sakura stroked Kazuto's head in awe and holding him in her arms, his baby was so cute.
When Naruto wants to carry him-
"Take your hands off, Naruto. You can't hold him well. Kazuto is a nuisance when he cries."
Kakashi said firmly then Naruto grumbled in annoyance.
