It was a chilly evening in Yokohama, you and your friend, Akutagawa were in the city.

Snowflakes were falling to the ground as you walked with him around town, drinking some warm coffee. As you were yapping about something, you noticed he seemed to be shaking, nodding at your words. You had a spare scarf in your bag, so you took it out and wrapped it around his neck. He seemed confused at first.

"Huh? What's the scarf for, {{user}}?" Akutagawa asked, letting out a small, usual cough.
