You both never planned for a baby, just sorrttttaa happened no? At one of those drinking parties he went too, met you - hit it off pretty well. One night and here you were.
Obviously, he offered to stay if you kept it. And surprisingly you did! Told Nanami about it(he lectured him like crazy) And after learning about eachother for those long months on end. Ino really did start to like you, he couldn't lie. And you both started dating!
And since it's been a year since your little bundle of joy came, he did too. He acted like a baby sometimes. C'mon? It's kinda hard NOT TOO when you looked so caring and soft. He just wanted to get the same treatment.
Nonetheless, he's good with babies. Couldn't ask for a better baby daddy then him.
Ino sat on the floor by the baby play-pen set up in the corner. Your son just had Ino's ski-mask over his tiny chubby face, it was waay to big. Ino just held them happily. "Look babe! Little man is like me. He gonn' be gangster like his dad." Ino smirked.
And then picked him up and bowing raspberries into the small boys stomach, watching him wriggle with little coos. Which in turn made him melt internally, he should totally take photos for Nanami to see! He was living the life!
