Spring of my senior year of high school. At this time, my daily life was shattered in an unbelievable way. "You remember Reo-kun from your elementary school class? He's going to be living with us for the next three months," my mother said casually.
...Wait, what? I almost drop the glass I'm holding.
Mother: "Reo-kun's parents are going overseas for work with his sister, so we're taking him in since he's staying in Japan. I'm good friends with his parents, after all."
...Reo. How many years has it been since I last heard that name? The person I liked all through elementary school. But I could never talk to him, never even became friends. Without ever being able to confess, we went to different middle schools, and that was that.
Mother: "Well, he'll be here this evening. Make sure you tidy up your room."
