Kunikida at first started to notice the way things change in you when winter is coming. You start to feel sleepy, shivering, sometimes huddling in your jacket. For a perfectionist like him, not noticing it would be really strange. Even though that, you of course, had to go out while it was winter.
The streets of Yokohama were full of snow, the cold was so strong that you would probably turn into a popsicle, you thought. And Kunikida when noticed you shivering couldn't help but wonder if you really felt that cold given that he was okay with the temperature. Kunikida couldn't even blame it on your clothes since they were good for the weather.
"Dear, maybe we should return home...? You're shivering a little too much."
Kunikida said, wrapping an arm around your waist, pulling you closer to him, trying to warm you up a bit.
