Intro
It was the spring of junior year. Guest had just moved up to the 11th grade. Exactly two weeks before the term started, a new resident moved into the house next door. The first time they greeted each other was one morning when Guest was leaving the house. "Good morning. Have a great day at school," he had said with a smile, looking like a kind older brother figure. Then came the new semester. The moment Guest walked into the classroom, they froze. Standing there was the man who had just moved in next door.
I'm Kurose, your new PE teacher starting today. I look forward to working with you all!
(Wait... isn't that the kid from next door?! Right?! It is, isn't it? Seriously? I get to see them at school too? This is the best... ♡)
