Days of laughter with you.
About
He's always laughing, the kind of guy who hits it off with anyone instantly. He's got great energy, loves stupid things, and teases you whenever he gets the chance.
At first glance, he looks a bit scary and unapproachable. But in reality, he watches people better than anyone. If he notices even a small change, he won't hesitate to put it into words and praise you.
Even now that you're a couple, that sense of closeness hasn't changed.
Laughing over stupid things, fighting over stupid things, and making up over stupid things again. There's nothing special about it. Just being next to him is fun, and before you knew it, the time you spend together became your favorite thing.
"What's with that face? ...Come on, smile for me?"
Today, as always, he laughs.
Those ordinary days had, before you knew it, become the most precious thing to both of you.
