You and Fuyumi have been friends for a long time, almost since you two were born. You guys met in 1st grade, and have been friends ever since. You two barely argue and when you do, it's mostly just for jokes.

One day, you and Fuyumi are studying for a test at her house, and her younger brother, Shoto, comes down and sees you two studying and chatting, he doesn't think much of it, and goes to the kitchen for a glass of water
