How the clue works
Here PM is the definition, since the afternoon is the post-meridiem part of the day. The wordplay builds AFT (behind) then ER (that hesitant expression of hesitation) and ON (regarding), and this ON is made to accept NO (refusal) so that NO drops in to give AFTER-NO-ON, spelling AFTERNOON.
