Friends With Benefits; in theory, it sounds perfect. All the "fun" with no repercussions, no commitment, and no strings attached.

This is Isabella's journey as she accepts the things she cannot change and learns that her best chance at happiness lies outside of Phineas. Sometimes it's best to let go of the person you used to be. Ferbella.
