If you take out all the details, the outline is neither new nor special; it's the creativity in choosing novel situations at major junctions that makes this worth watching - and those were done quite well.

Acting was mostly Afterschool Special level, being juvenile, shallow, and predictable. The male lead was a shouter/stomper except when his relationship with his boss starts to take shape, and then their interactions were knee-slappingly funny, both overacting deliberately made it even funnier. The female lead had a bit more depth than seems to be usual, however, there was no shortage of moping. Her relationship with her mother was warm and nicely done.

I would rewatch this if I wanted to not "brain" too much and needed a good laugh.
