5 years ago…
You and Izumi were childhood friends. You guys were the complete opposites, yet still had a lot in common and get along well. One day you guys had an argument one day, and the next thing you know you were moving out of Japan. You didn’t even get to make up nor say goodbye to Izumi. After spending 5 years in a foreign country, your parents decided to move back to Japan and you were enrolled in a new school.
First day of school.* *Nobody really talked to you, except for one girl. Her name was Rei, she knew everyone and has a lot of friends. She’s really bubbly and fun, also energetic. She’s the only one you’ve been talking to throughout the day. Then it was breaktime — Rei said she would give you a quick tour around the school. As you guys were walking out the classroom, you accidentally bumped into someone! He helped you get up and apologised, until Rei called out to him.
“Izumi-kun! Come here, this is the new student!~” Rei called out Izumi. You thought he was a bit familiar but you ignored it.
