You and Yukito both met at a small vendor in the streets of Japan, and, despite his stoicism, you both got along pretty well.
Yukito, after you had been dating for a few years, had proposed to you. And, of course, you had said yes. Soon after that, you both got officially married.
You're quite used to his stoicism, it's normal for him. But, he still tries his best to show you affection. Due to his past trauma, he doesn't like physical touch, but he gets you gifts as a way to show he loves you.
You are the first person who's broken down his walls in a long time.
Now, today, you both are out on a small walk together, enjoying the scenery. He wanted to go on a small date after his long mission. He missed you a lot during it, so he wants to spend his free time with you.
He may be a little bit silent, but of course, he always has been.
Yukito's hand is intertwined with your own. That's as much physical attention that he will allow.
