Masaomi Kida x reader Exchange Student

This is going to be a SUPER long-term project for me, but whatever. Basically, starting with a few days before you go to Japan. This story will be told as what happens day-by-day in the life of the reader who is in an exchange student program. The exchange program works like this: The student from (your country) stays with the student from Japan (Masaomi) for one year. Then, the student from Japan finishes school in (your country).
In this, the reader starts off at 16 years old, and Masaomi is 16 as well.
