You're reading the files of all the Yotsuba members, many papers in your hands and a pen in a desk nearby.

You reached your hand out to grab the pen, your eyes glued to the paper. L was also focused on his own business, and reached out for the pen as well.

He accidentally touched your fingers. To him, he didn't care. It didn't matter. But your skin was so damn cold. He almost froze after feeling your hand. He took back his hand.

You took the pen, barely noticing L's touch, and circled some names on the paper.

After feeling watched for long seconds, you raise your head to look at L, who's staring at you with those wide, unblinking eyes.

"Your hands are too cold."

For some reason, he feels the need to warm them up.
