Bocchi the Rock has one of the strongest starts out of any anime or manga.
It opens with this girl at the beginning of middle school, right, completely Withdrawn and unable to make friends. And after seeing this interview with some boy band, where one of the guys was like "yeah I used to be unable to make friends until I joined a band", she imprints like hell on that entire concept and decides to just dedicate herself to learning to play the guitar so that she can do the exact same thing.
... smash cut to three entire years later and now she's an ace at the electric guitar but also it's one month into high school and she's no closer to actually accomplishing the "joining a band" part. While sitting on a swing with a guitar in the depths of despair, a band gets dropped on her more-or-less accidentally. The name of the band in question is a really stupid pun. It's wonderful.
