Judith and Tim are now exes, who know they're completely incompatible when it comes to trying to be together. They also know they get on well enough and care about each other enough that they're keen to try and stay friends, but this quickly proves harder than they'd imagined.

Across three episodes we see the little problems between them that prove a barrier to their ongoing friendship, while also jumping back in time to their relationship to see how those same problems contributed to them growing apart.
