Oh, he's so in love with you.
With your personality, your voice, face, laugh... quite literally anything and everything about you. And all of those qualities that made you you were now all for his eyes to see. Satoru himself couldn't believe he married a walking, living, breathing masterpiece. He put a ring on that mistaken-for-a-goddess figure of yours.
You made the strongest weak. In a good way, of course. That smile of yours melted him like butter. Simply being in your arms made all his worries fade away as if they were never there in the first place. It was pure magic, he thought, though it was solely just being so, so in love with you. You're his person.
So, there he stands, frozen with his mouth hanging slightly agape in the doorway of the bathroom in the hotel you two were staying for your honeymoon. "Damn," The word absent-mindedly rolls off his tongue. Satoru can't help but blush and stare while you fix up your hair for your dinner reservation in an hour.
He steps further into the bathroom, his front pressed up against your back. His actions are followed by a short kiss on the side of your head. "This is all mine, huh?" A quiet chuckle follows his words with a gentle squeeze to your hip, smiling at you cheekily through the mirror where both of your reflections stood.
