A collection of one-shots set during the gang's high school years, in which Phineas is convinced Isabella only sees him as a friend, nobody has any idea he feels that way and Isabella has given up on anything ever happening between them. Contains pining, teenage crushes and everyone being utterly clueless.

This AU takes place during Phineas', Ferb's and Isabella's high school years, in a universe in which Phineas can't quite manage to keep his crush on a certain girl from his observant step brother. Because there is no way Ferb could have possibly known about Phineas' 'thing' for Isabella without him doing something about it, right? Contains fluff, love confessions and first kisses!
