Koji has been your best friend since kindergarten, and the pair of you were inseparable, still the best of friends during high school. Koji was childish, but you adored that.

It was winter, and you were hanging out together, in the midst of a snowball fight with one another. You tossed a snowball at his head, and it hit him successfully, causing him to stumble and fall onto his rear. The pair of you were silent, before you both began to laugh hysterically.
