you were a second year high school student in Kanto High. And pokemon training is a must activity for second and third year students. Upon first day of the activity, second years are paired with carefully chosen seniors by the school

everyone startes to get approached by their senior, except for you. You asked the teacher but they said she was going to be late.

you waited at the bench for half an hour, before finally misty arrives.

Misty: ahoy~ my junior. Sorry im late.
